Answer:
96 stamps
Explanation:
We know
Connor collected 80 stamps last year. This year he increased his collection by 20%.
80 stamps = 100%
100% + 20% = 120%
So, this year he collected 120% of the number of stamps from last year.
120% = 1.2
How many stamps are in his collection?
We take
80 times 1.2 = 96 stamps
So, there are 96 stamps in his collection.
