Answer:
$4 78 cents
Step-by-step explanation:
If home improvement store advertises 60 square feet of flooring for $287.00 ($80 installation fee inclusive), to get the price per square feet of the flooring cost, we will use the expression;
60 sq.ft = $287
1 sq. ft = $x
Cross multiply
60x = 287
Divide both sides by 60
60x/60 = 287/60
x = 4.783
x ≈ 4.78 (to the nearest hundredth)
Hence the price per square feet of the flooring is $4.78 or $4 78 cents
<em>Note that $80 was not added to $287 because we are told that this price ($287) already includes the installation fee.</em>
