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 |
Comparing biscuits
and tarts in the end |
|
93 more |
0.7 =
710 25 x 60 = 24
Number of tarts that Aunt Natalie gave to Linda = 4 u + 24
If Aunt Natalie made another 93 biscuits in the end, the number of biscuits and tarts in the end would be the same.
6 u + 36 = 3 u + 93
6 u - 3 u = 93 - 36
3 u = 57
1 u = 57 ÷ 3 = 19
Number of biscuits that Aunt Natalie made
= 10 u
= 10 x 19
= 190
Answer(s): 190
