Question
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 evaluate for l = 4 and w = 6, substitute the values into the expression 25l + 20w:
25(4) + 20(6)
= 100 + 120
= 220
Jaden will earn $220 for 4 lawn-mowing jobs and 6 pulling-weeds jobs.

To find how much money Jaden will earn for 4 lawn-mowing jobs and 6 pulling-weeds jobs, we can substitute l = 4 and w = 6 into the expression 25l + 20w:
25(4) + 20(6) = 100 + 120 = 220
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 evaluate for s = 10, substitute the value into the formula 6s^2:
6(10)^2 = 6(100) = 600
The surface area of the cube with a side length of 10 cm is 600 square centimeters.
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 evaluate for h = 3, substitute the value into the expression 65h + 100:
65(3) + 100 = 195 + 100 = 295
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.
To evaluate for t = 2, substitute the value into the formula 75 - 16t^2:
75 - 16(2)^2 = 75 - 16(4) = 75 - 64 = 11
The diver is 11 feet above the ocean in 2 seconds.
