A home improvement store advertises 60 square feet of flooring for $287.00. The price includes an $80.00 installation fee. How much does each square feet of flooring cost, including the installation fee? Your answer, in dollars and cents, should be a decimal rounded to the nearest hundredth (penny).

$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

Note that $80 was not added to $287 because we are told that this price ($287) already includes the installation fee.

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.

answer: sine
