Jen bought some eggs to bake cakes for a party. If she used 10 eggs for each cake, she would be short of 16 more eggs to bake all cakes. If she used 14 eggs for each cake, she would be short of 56 more eggs.
- How many cakes did she bake?
- How many eggs did Jen buy?
(a)
Small difference
= 14 - 10
= 4
Big difference
= 56 - 16
= 40
Number of cakes that Jen bought
= 40 ÷ 4
= 10
(b)
Number of eggs that Jen bought
= 10 x 10 - 16
= 100 - 16
= 84
Answer(s): (a) 10; (b) 84
