Xylia had 12 more cupcakes than Victoria at first. After Xylia ate 3 cupcakes, she had four times as many cupcakes as Victoria in the end. How many cupcakes did Victoria have?
| |
Victoria |
Xylia |
| Before |
1 u |
1 u + 12 |
| Change |
|
- 3 |
| After |
1 u |
1 u + 9 |
Comparing Victoria
and Xylia in the end |
1 u |
4 u |
The number of cupcakes that Victoria had remains unchanged.
Number of cupcakes that Xylia had in the end
= 4 x 1 u
= 4 u
4 u = 1 u + 9
4 u - 1 u = 9
3 u = 9
1 u = 9 ÷ 3 = 3
Number of cupcakes that Victoria had
= 1 u
= 3
Answer(s): 3
