Mrs Charlie baked some croissants. She gave
37 of the croissants to her best friend and
38 of the remainder to her uncle. Given that she gave 18 less croissants to her uncle than her best friend. How many croissants did
she bake at first?
Best Friend |
Remainder |
Total |
3x2 |
4x2 |
7x2 |
|
Uncle |
Left |
|
6 u |
3 u |
5 u |
14 u |
Number of less croissants that Mrs Charlie gave to her uncle than her best friend
= 6 u - 3 u
= 3 u
3 u = 18
1 u = 18 ÷ 3 = 6
Number of croissants that Mrs Charlie baked at first
= 14 u
= 14 x 6
= 84
Answer(s): 84
