Question

A collector has 105 movie posters and 90 band posters. She wants to sell 28 movie posters but still have her poster collection maintain the same ratio of 105:90. If she sells 28 movie posters, how many band posters should she sell? Complete the explanation to find out how many band posters she should sell.

Answer 1

24

Explanation:

So, first subtract 105-28=77

Now simplify the ratio given. 105:90=21:18=7:6

So she has 77:90 right now. You want it to be 77:66 to fit the ratio.

She should sell 24 band posters.
