Question

The number of measles cases increased 5.2% to 33 cases this year, what was the number of cases prior to the increase?

Answer 1

31.284 or if you rounded to the nearest whole number it would be 31

Explanation:

5.2% -> 0.052

33x0.052=1.716

33-1.716= 31.284

(I'm not 100% sure if this is right, but let me know if you get this right or wrong on your test.)

Answer 2

x(1.052)= 33

x = 33/1.052 =31.36
