Jaslyn baked 40 tarts.
35 of the tarts were mocha tarts. The rest were peach tarts. She gave an equal number of mocha tarts and peach tarts away and had 5 times as many mocha tarts as peach tarts left. How many tarts did she give away?

Mocha tarts |
Peach tarts |
Difference |
Before |
3x4 = 12 u |
2x4 = 8 u |
1x4 = 4 u |
Change |
- 7 u |
- 7 u |
|
After |
5x1 = 5 u |
1x1 = 1 u |
4x1 = 4 u |
Since Jaslyn gave away an equal number of mocha tarts and peach tarts, the difference in the number of mocha tarts and peach tarts remains unchanged. Make the difference in the mocha tarts and peach tarts the same. LCM of 1 and 4 is 4.
Total number of tarts at first
= 12 u + 8 u
= 20 u
20 u = 40
1 u = 40 ÷ 20 = 2
Number of tarts that Jaslyn gave away
= 7 u + 7 u
= 14 u
= 14 x 2
= 28
Answer(s): 28
