Question

10. A home improvement store advertises 60

Answer 1

Answer:

cost for (not per) 1 sq ft. floor: $84.79

y = total costs

x = sq ft of flooring

y = x4.79 + 80.00

Step-by-step explanation:

i this equation, y = the total cost wile x = square ft. of flooring

to find out the price when we know that 60 sq ft is $287.00 without the instalation fee, all we have to do is divide 287.00 by 60

287 / 60 = 4.79

so we now know how much 1 sq ft. costs, but to implament it into an equation we need to multiply it by the amount of flooring, so we let x be the number of sq ft used

now all we have to do is add the instalation fee, no, we literally add it in the equation at the end, so that it is added after we multiply by sq ft (not before) then after we calculate that, we get the total cost for x sq ft of flooring, or y

hope this answers your question
