find the percent

Question

Suppose one hundred eleven people who shopped in a special t-shirt store were asked the number of t-shirts they own costing more than $19 each.

Find the percent of people that own at most four t-shirts costing more than $19 each. (Round your answer to a whole number.)

________ %

Answer 1

You are looking for those who own at most 4 t-shirts costing $19.

There are:

5 that own 1 t-shirt that costs $19 or more;

17 that own 2 t-shirts that costs $19 or more;

23 that own 3 t-shirts that cost $19 or more;

39 that own 4 t-shirts that cost $19 or more.

Sum those numbers up: 5+17+23+39=84.

But you want a percent. First you would divide 84/111 = .7568 (rounding). Then multiply that answer .7568 by 100 (move the decimal to the right twice: 75.68%. Rounding to the nearest, that is 76%.
