Tina had 8 more cupcakes than Eva at first. After Tina ate 4 cupcakes, she had five times as many cupcakes as Eva in the end. How many cupcakes did Eva have?
| |
Eva |
Tina |
| Before |
1 u |
1 u + 8 |
| Change |
|
- 4 |
| After |
1 u |
1 u + 4 |
Comparing Eva
and Tina in the end |
1 u |
5 u |
The number of cupcakes that Eva had remains unchanged.
Number of cupcakes that Tina had in the end
= 5 x 1 u
= 5 u
5 u = 1 u + 4
5 u - 1 u = 4
4 u = 4
1 u = 4 ÷ 4 = 1
Number of cupcakes that Eva had
= 1 u
= 1
Answer(s): 1
