You just need to replace x with 100 in the formula and do the math.

anonymous · Answer

so it would be 0.765(100)+0.06(0.765(100))?

Let me check

anonymous · Answer

No. 0.765(100) is 76.5. So you now have 76.5 + 0.06(76.5). 0.06(76.5) = 4.59 (calculator). So 76.5 + 4.59 = 81.09. The answer is $81.09.

In this particular case, you should have realized (so should I) that 153.06 couldn't be right because it was more than the original price of the coat before the sale!
