Yoko bought some eggs to bake cakes for a party. If she used 4 eggs for each cake, she would be short of 4 more eggs to bake all cakes. If she used 7 eggs for each cake, she would be short of 61 more eggs.
- How many cakes did she bake?
- How many eggs did Yoko buy?
(a)
Small difference
= 7 - 4
= 3
Big difference
= 61 - 4
= 57
Number of cakes that Yoko bought
= 57 ÷ 3
= 19
(b)
Number of eggs that Yoko bought
= 19 x 4 - 4
= 76 - 4
= 72
Answer(s): (a) 19; (b) 72
