(a)
Cost of 1 cupcake = 1 u
Cost of 1 strudel = 3 u
Cost of 6 cupcakes
= 6 x 1 u
= 6 u
Cost of 8 strudels
= 8 x 3 u
= 24 u
Total cost of 6 cupcakes and 8 strudels
= 6 u + 24 u
= 30 u
$1 = 100¢
$6 = 6 x 100 = 600¢
30 u = 600
1 u = 600 ÷ 30 = 20
Cost of a bun
= 1 u
= 20¢
(b)
Amount that Irene paid more for a strudel than a cupcake
= 6 u - 1 u
= 5 u
= 5 x 20
= 100¢
100¢ = $1
Answer(s): (a) 20¢ (b) $1
