C = 0.765x + .06(0.765x)
C = 0.765(100) + .06(0.765(100)
C = 76.5 + .06(76.5)
C = 76.5 + 4.59
C = 81.09

@jim_thompson5910 ......can you take a peek at this......do I still need to take off the discounts......or did I do it correctly by just following the equation ?

jim_thompson5910 · Answer

the discounts were already calculated and applied when they came up with this equation

jim_thompson5910 · Answer

so that saves you from having to figure out the overall discount percentage or anything like that

which means all you have to do is plug in x = 100 and evaluate
