Ivory bought some eggs to bake cakes for a party. If she used 7 eggs for each cake, she would be short of 9 more eggs to bake all cakes. If she used 11 eggs for each cake, she would be short of 57 more eggs.
- How many cakes did she bake?
- How many eggs did Ivory buy?
(a)
Small difference
= 11 - 7
= 4
Big difference
= 57 - 9
= 48
Number of cakes that Ivory bought
= 48 ÷ 4
= 12
(b)
Number of eggs that Ivory bought
= 12 x 7 - 9
= 84 - 9
= 75
Answer(s): (a) 12; (b) 75
