Kimberly bought some eggs to bake cakes for a party. If she used 8 eggs for each cake, she would be short of 5 more eggs to bake all cakes. If she used 13 eggs for each cake, she would be short of 65 more eggs.
- How many cakes did she bake?
- How many eggs did Kimberly buy?
(a)
Small difference
= 13 - 8
= 5
Big difference
= 65 - 5
= 60
Number of cakes that Kimberly bought
= 60 ÷ 5
= 12
(b)
Number of eggs that Kimberly bought
= 12 x 8 - 5
= 96 - 5
= 91
Answer(s): (a) 12; (b) 91
