Mrs Sean baked some shortbreads. She gave
35 of the shortbreads to her niece and
34 of the remainder to her best friend. Given that she gave 15 less shortbreads to her best friend than her niece. How many shortbreads did
she bake at first?

|
| 6 u |
3 u |
1 u |
10 u |
Number of less shortbreads that Mrs Sean gave to her best friend than her niece
= 6 u - 3 u
= 3 u
3 u = 15
1 u = 15 ÷ 3 = 5
Number of shortbreads that Mrs Sean baked at first
= 10 u
= 10 x 5
= 50
