Allison's 11th birthday is just around the corner. Her parents are remodeling her bedroom for her birthday. They will replace her carpet and repaint her walls
Allison's Room
Height 8ft
Width 11ft
Length 13ft
1.Allison wants the top 1/2 of her walls painted pink and the bottom 1/2 painted purple. How many square feet will be pink?
2.If one can of paint will cover 80 square feet,how many cans of paint will they need to buy to cover half her walls purple and the other half pink?
3.If a can of pain cost $14 and carpet cost $2 a square foot,how much money will Allison's parents spend on remodeling her bedroom?
I don't get how to answer all of these
1.
Two walls:
A = L * W
A = 2(11 * 8)
A = 176 sq. ft.
Other two walls:
A = 2 (13 * 8)
A = 208 sq. ft.
Pink:
(176 + 208)/2 = 192 sq. ft/
2.
192/80 = 2.4 = 3 cans of each color
3.
I'll be glad to check your answer.
Whats the 2 for on A = 2(11 * 8) and
A = 2 (13 * 8) ?
The 2 means to multiply. The room has 4 walls; 2 are one size and the other 2 are another size.
* means to divide?
I got #1 for number 3 is the answer $202? I multiplied 14 and 3 and 80 and 2 then I added the product and got 202
* = multiply
Multiply the number of cans of paint by $14.
Multiply the number of square feet for the carpet by $2.
To answer these questions, let's break down each one step by step.
1. How many square feet will be pink?
To calculate the square footage of the top half of the walls, you need to find the area of half of the room's walls. Since the height of the room is 8 feet, and the length of the room is 13 feet, you can calculate the area of each wall using the formula for the area of a rectangle: Area = length x height.
Since there are four walls in the room, you need to calculate the area of two walls. So, for each wall, the area would be: 13 ft x 8 ft = 104 square feet.
Now, since you only need the top half of each wall painted pink, you would need to find half of the area calculated above. Therefore, the square footage that will be pink is: (104 square feet / 2) x 2 walls = 104 square feet.
2. How many cans of paint will they need to buy?
Since each can of paint can cover 80 square feet, you need to calculate the total square footage of both the pink and purple halves of the walls.
To find the total square footage of the walls, you need to add the areas of the two halves of the walls calculated previously. So, 104 square feet for the pink walls + 104 square feet for the purple walls = 208 square feet.
Next, divide the total square footage by the coverage area of each can of paint: 208 square feet / 80 square feet per can = 2.6. Since you can't purchase a fraction of a can, you would need to round up to the nearest whole number. Therefore, they would need to buy 3 cans of paint.
3. How much money will Allison's parents spend on remodeling her bedroom?
To calculate the cost of painting, multiply the cost per can of paint by the number of cans needed. So, $14 per can x 3 cans of paint = $42 for painting.
To calculate the cost of carpeting, you need to find the area of the floor. The area of the floor can be found using the same formula as before: Area = length x width. So, the area of the floor is: 11 ft x 13 ft = 143 square feet.
Multiply the area of the floor by the cost per square foot of the carpet to find the total cost: 143 square feet x $2 per square foot = $286 for carpeting.
Finally, add the cost of painting and carpeting together to get the total cost of remodeling Allison's bedroom: $42 for painting + $286 for carpeting = $328.
So, Allison's parents will spend $328 on remodeling her bedroom.
