Answer:
80% decrease
Step-by-step explanation:
Find out how much percent each candy is worth:
100/15 = 6.67%
Find out how many pieces she gave away:
15 - 3 = 12
Multiply the pieces gave away by the percent per piece:
12 x 6.67 = 80.04
Round to the nearest whole number.
When using a calculator for 100/15 and then multiply by 12 you get exactly 80.
