17. a carpet cleaner charges $0.70 per square foot to clean carpet. in the next house she is going to clean, the living room measures 18 feet by 24 feet. how much will she charge?

Answer

Explanation:

Step1: Calculate the area of the living - room

The living - room is a rectangle with length $l = 24$ feet and width $w = 18$ feet. The area formula for a rectangle is $A=l\times w$. So, $A = 18\times24=432$ square feet.

Step2: Calculate the total charge

The carpet cleaner charges $0.70$ per square foot. Let $C$ be the total charge. Then $C=0.70\times A$. Substitute $A = 432$ into the formula: $C = 0.70\times432 = 302.4$.

Answer:

$302.4$
