Mrs Pierre baked some croissants. She gave
38 of the croissants to her friend and
320 of the remainder to her father. Given that she gave 36 less croissants to her father than her friend. How many croissants did
she bake at first?
| Friend |

| 3x4 |
5x4 |
8x4 |

Father |
Left |
|
| 12 u |
3 u |
17 u |
32 u |
Number of less croissants that Mrs Pierre gave to her father than her friend
= 12 u - 3 u
= 9 u
9 u = 36
1 u = 36 ÷ 9 = 4
Number of croissants that Mrs Pierre baked at first
= 32 u
= 32 x 4
= 128
Answer(s): 128
