Lynn bought some eggs to bake cakes for a party. If she used 10 eggs for each cake, she would be short of 18 more eggs to bake all cakes. If she used 12 eggs for each cake, she would be short of 58 more eggs.
- How many cakes did she bake?
- How many eggs did Lynn buy?
(a)
Small difference
= 12 - 10
= 2
Big difference
= 58 - 18
= 40
Number of cakes that Lynn bought
= 40 ÷ 2
= 20
(b)
Number of eggs that Lynn bought
= 20 x 10 - 18
= 200 - 18
= 182
Answer(s): (a) 20; (b) 182
