Question

Erica collected a total of $180 for her favorite charity over the first 3 months of the year. She collected the same amount in the first and second months. She collected three times the first month’s amount in the third month. How much money did she collect in the third month?

a) $36

b) $60

c) $120

d) $108

Answer 1

The answer is D:
180 - 108 = 72
72 ÷ 2 = 36

To check our answer:
108 ÷ 36 = 3
so 108 is 3 times as much as 36, which was the other 2 months.

Answer 2

x+x+3x= 180
5x= 180
x= 36

3(36)= 108
Your answer is D. $108
