If Sandy usually earns $88 plus 11% sales each week. What if she earns $154 one week. What is the % sales she earned that week when she earned $154?
Would the answer be 600?

Ms. Sue,
Yes. That's correct.

Amy~,
Would you know how to get the answer 600 because I solved it differently and did not get 600

Math 
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 
Math 
Ms. Sue,
Your fractions for the proportion are not equivalent.
Do you understand what I did?

yes
