Emily had 16 more mini cupcakes than Ian at first. After Ian had eaten 20 of his mini cupcakes, Emily had 5 times as many mini cupcakes as Ian. How many mini cupcakes did Emily and Ian have in total at first?
| |
Emily |
Ian |
Total |
| Before |
1 u + 20 + 16 |
1 u + 20 |
6 u + 20 |
| Change |
|
- 20 |
|
| After |
5 u |
1 u |
|
The number of mini cupcakes that Emily had at first remains unchanged.
5 u = 1 u + 20 + 16
5 u - 1 u = 36
4 u = 36
1 u = 36 ÷ 4 = 9
Number of mini cupcakes that they had at first
= 6 u + 20
= 6 x 9 + 20
= 54 + 20
= 74
Answer(s): 74
