Yes. That's correct.

Would you know how to get the answer 600 because I solved it differently and did not get 600
Ms. Sue
Here's what I did.

154 - 88 = 66

0.11x = 66
x = 600

I thought I had cross multiply.
88/154 = .11/x
Ms. Sue
Your fractions for the proportion are not equivalent.

Do you understand what I did?
