Mrs Dylan baked some biscuits. She gave
37 of the biscuits to her auntie and
38 of the remainder to her buddy. Given that she gave 15 less biscuits to her buddy than her auntie. How many biscuits did
she bake at first?

|
| 6 u |
3 u |
5 u |
14 u |
Number of less biscuits that Mrs Dylan gave to her buddy than her auntie
= 6 u - 3 u
= 3 u
3 u = 15
1 u = 15 ÷ 3 = 5
Number of biscuits that Mrs Dylan baked at first
= 14 u
= 14 x 5
= 70
