Question

Last year 80 students signed up for a summer trip to Washington, DC. This summer 50 students have signed up to go. What is the percent decrease in the number of students?

Answer 1

The decrease percent is 30% why? Well because you subtract 80 minus 50 which equals 30 so it's 30%

Answer 2

50/80 = 0.625

100 - 0.625 = 0.375

0.375 = 37.5% (move the decimal point to the right 2 spaces)

37.5% decrease is your answer

hope this helps
