A strudel cost five times as much as a muffin at a nearby food outlet. Flynn spent 14 of his money on some muffins and half of the remaining sum on 3 strudels. He had $18 left.
- What was the cost of 1 muffin?
- Perry bought 4 strudels and 5 muffins. How much did he spend altogether?
(a)
Fraction of Flynn's amount left after buying the muffins
= 1 -
14 =
34 Fraction of Flynn's amount spent on the strudels
=
34 x
12 =
38 Fraction of money left
= 1 -
14 -
38 = 1 -
28 -
38 =
38 Amount that Flynn had left = 3 u
3 u = 18
1 u = 18 ÷ 3 = 6
Amount that Flynn had left = Amount spent on 3 strudels
Cost of 3 strudels = $18
Cost of 1 strudel = 18 ÷ 3 = $6
Cost of 1 strudel is 5 times as much as the cost of 1 muffin.
Cost of 1 muffin
= 6 ÷ 5
= $1.20
(b)
Cost of 4 strudels and 5 muffins
= 4 x 6 + 5 x 1.20
= 24 + 6
= $30
Answer(s): (a) $1.20; (b) $30
