Answer:
Ava had a greater percentage of change because her allowance increased by 150%, while Joey's only increased by 133%
Step-by-step explanation:
To find the percentage of change, you'll divide.
For Ava:
18 ÷ 12 = 1.5
This means her percentage of change is 150%
For Joey:
24 ÷ 18 = 1.33333... (Round to 1.33)
This means his percentage of change is 133%
150% > 133%, so Ava has the greater percentage of change.
