danjs · Answer

x =  original price of the sofa

danjs · Answer

With "Only the three dollar discount" the function will be the original cost, take away 3 dollars or 

f(x) = x - 3

danjs · Answer

if you were to include the 35% off with that 3 dollars off , it would be 

f(x) = (0.65)x - 3

"65 percent of the original cost minus 3 dollars"

Form the composition of the functions f
and that represents your cost if you use the
discount first, then use the coupon
 this is another part 
I assumed it would be 0.65x-3

danjs · Answer

Discount First, Then the coupon -  0.65x - 3

Coupon first then the Discount -  0.65(x-3)
