Jaden has a part-time job working for a landscaping company. He earns $25 for each lawn-mowing job, l , and $20 for each pulling-weeds job, w . This can be modeled by 25l+20w . Evaluate for l=4 and w=6 to find how much money Jaden will earn for 4 lawn-mowing jobs and 6 pulling-weeds jobs. (1 point)
To find how much money Jaden will earn for 4 lawn-mowing jobs and 6 pulling-weeds jobs, substitute l = 4 and w = 6 into the expression 25l + 20w:
25(4) + 20(6)
= 100 + 120
= 220
Therefore, Jaden will earn $220 for 4 lawn-mowing jobs and 6 pulling-weeds jobs.
The formula for finding the surface area of a cube is 6s2 , where s is the length of each side of the square. Evaluate for s=10 to find the number of square centimeters ( cm2 ) for the surface area of a cube with a side length of 10 cm. (1 point)
To find the surface area of a cube with a side length of 10 cm, substitute s = 10 into the formula 6s^2:
6(10)^2
= 6(100)
= 600
Therefore, the surface area of a cube with a side length of 10 cm is 600 cm^2.
Alicia works for Thomas Edison Electrical Company. She earns $100 for going to a customer’s house and $65 per hour, h , for the job. This is modeled by 65h+100 . Evaluate for h=3 to find how much Alicia will earn for a job that takes 3 hours.(1 point)
To find how much Alicia will earn for a job that takes 3 hours, substitute h = 3 into the expression 65h + 100:
65(3) + 100
= 195 + 100
= 295
Therefore, Alicia will earn $295 for a job that takes 3 hours.
A competitive cliff-diver jumps from a height of 75 feet. Find the number of feet the diver is above the ocean in 2 seconds. Evaluate for t=2 by using the formula 75−16t2 , where t is time in seconds. (1 point)
To find the number of feet the diver is above the ocean in 2 seconds, substitute t = 2 into the formula 75 - 16t^2:
75 - 16(2)^2
= 75 - 16(4)
= 75 - 64
= 11
Therefore, the diver is 11 feet above the ocean in 2 seconds.
Gabrielle wants to put a border around her garden. It costs $1.50 per yard for the materials. Use 1.50(2l+2w) , where l is the length and w is the width of her garden, to find the cost for a garden that has a length of 4 yards and a width of 3 yards.(1 point)
To find the cost for Gabrielle's garden border, substitute l = 4 and w = 3 into the expression 1.50(2l + 2w):
1.50(2(4) + 2(3))
= 1.50(8 + 6)
= 1.50(14)
= 21
Therefore, the cost for Gabrielle's garden border is $21.
Mr. Imani wants to purchase paper and notebooks for his classroom. At Dollar Discount he can buy packs of paper, p , for $1.25 each and notebooks, n , for $2.50 each. This is modeled by 1.25p + 2.50n . Evaluate for p = 10 and n=30 to find how much it will cost Mr. Imani to purchase 10 packs of paper and 30 notebooks. (1 point)

To find how much it will cost Mr. Imani to purchase 10 packs of paper and 30 notebooks, substitute p = 10 and n = 30 into the expression 1.25p + 2.50n:
1.25(10) + 2.50(30)
= 12.50 + 75
= 87.50
Therefore, it will cost Mr. Imani $87.50 to purchase 10 packs of paper and 30 notebooks.
The formula for finding the volume of a square prism is s2h , where s is the length of each side of the square base and h is the height of the prism. Evaluate to find the volume given values of s = 4 and h = 6 .(1 point)

To find the volume of a square prism with side length 4 and height 6, substitute s = 4 and h = 6 into the formula s^2h:
(4)^2 * 6
= 16 * 6
= 96
Therefore, the volume of the square prism is 96 cubic centimeters.
Each month Ms. Tanaka is paid a base salary of $2,500 in addition to $100 for each television that she sells. This is modeled by 2,500 + 100t , where t represents the number of televisions. Evaluate for t = 12 to find how much Ms. Tanaka will earn for selling 12 televisions this month.(1 point)

= 3,700
Therefore, Ms. Tanaka will earn $3,700 for selling 12 televisions this month.
Robert is preparing a poster-board presentation. He wants to make a decorative pattern with 10 squares to fill part of the poster. The area of the poster board is 720 square inches. To find how much space Robert will have left for his presentation if he uses squares with 7-inch sides, evaluate 720 − 10s2 when s = 7 .(1 point)

34,790 square inches

230 square inches
To find how much space Robert will have left for his presentation, we need to subtract the total area of the 10 squares from the area of the poster board. The formula to find the area of a square is s^2, where s is the length of each side.
Given that s = 7, we can calculate the area of each square as 7^2 = 49 square inches.
To find the total area of the 10 squares, we multiply 49 square inches by 10: 49 * 10 = 490 square inches.
Now we can find how much space is left for the presentation by subtracting the area of the squares from the area of the poster board: 720 - 490 = 230 square inches.
Therefore, Robert will have 230 square inches left for his presentation.
Mr. Rodriguez has a vegetable garden that borders his house. He wants to put a fence around it. It costs $7 per yard for the materials.
