Hilda bought some eggs to bake cakes for a party. If she used 7 eggs for each cake, she would be short of 11 more eggs to bake all cakes. If she used 10 eggs for each cake, she would be short of 44 more eggs.
- How many cakes did she bake?
- How many eggs did Hilda buy?
(a)
Small difference
= 10 - 7
= 3
Big difference
= 44 - 11
= 33
Number of cakes that Hilda bought
= 33 ÷ 3
= 11
(b)
Number of eggs that Hilda bought
= 11 x 7 - 11
= 77 - 11
= 66
Answer(s): (a) 11; (b) 66
