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?

    Yes. That's correct.

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

  • Math - ,

    Here's what I did.

    154 - 88 = 66

    0.11x = 66
    x = 600

  • Math - ,

    I thought I had cross multiply.
    88/154 = .11/x

  • Math - ,

    Your fractions for the proportion are not equivalent.

    Do you understand what I did?

  • Math - ,

    yes
