Yen 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 11 eggs for each cake, she would be short of 63 more eggs.
- How many cakes did she bake?
- How many eggs did Yen buy?
(a)
Small difference
= 11 - 7
= 4
Big difference
= 63 - 11
= 52
Number of cakes that Yen bought
= 52 ÷ 4
= 13
(b)
Number of eggs that Yen bought
= 13 x 7 - 11
= 91 - 11
= 80
Answer(s): (a) 13; (b) 80
