Gwen bought some eggs to bake cakes for a party. If she used 6 eggs for each cake, she would be short of 7 more eggs to bake all cakes. If she used 10 eggs for each cake, she would be short of 47 more eggs.
- How many cakes did she bake?
- How many eggs did Gwen buy?
(a)
Small difference
= 10 - 6
= 4
Big difference
= 47 - 7
= 40
Number of cakes that Gwen bought
= 40 ÷ 4
= 10
(b)
Number of eggs that Gwen bought
= 10 x 6 - 7
= 60 - 7
= 53
Answer(s): (a) 10; (b) 53
