60 more |
Before |
10 u |
5x2 + 60 =
10 u + 60 |
Change |
- 7 u |
- 2x2 - 24 =
- 4 u - 24
|
After |
3 u |
3x2 + 36 =
6 u + 36 |

and puffs in the end |

60 more |
0.7 =
710 25 x 60 = 24
Number of puffs that Aunt Linda gave to Penelope = 4 u + 24
If Aunt Linda made another 60 macarons in the end, the number of macarons and puffs in the end would be the same.
6 u + 36 = 3 u + 60
6 u - 3 u = 60 - 36
3 u = 24
1 u = 24 ÷ 3 = 8
Number of macarons that Aunt Linda made
= 10 u
= 10 x 8
= 80
Answer(s): 80
