Answer 1

The insulation fee for 175 square feet of carpet is $237.

Explanation:

The amount of money, f(x), that it cost to purchase x square feet of the carpet is:

f(x)= 8x

The insulation fee,g(x), is $125 more than 8% of the cost of the carpet,f(x), we have

g(x)=8% of f(x)+125

`\Rightarrow=(8)/(100)* (8x)+125`

`\Rightarrow=0.64x+125`

The insulation fee for 175 square feet of carpet,

i.e for x=175

`g(x=175)=0.64*175+125=237`

Hence, the insulation fee for 175 square feet of carpet is $237.
