(a)
Cost of 1 tart = 1 u
Cost of 1 strudel = 3 u
Cost of 6 tarts
= 6 x 1 u
= 6 u
Cost of 3 strudels
= 3 x 3 u
= 9 u
Total cost of 6 tarts and 3 strudels
= 6 u + 9 u
= 15 u
$1 = 100¢
$3 = 3 x 100 = 300¢
15 u = 300
1 u = 300 ÷ 15 = 20
Cost of a bun
= 1 u
= 20¢
(b)
Amount that Dana paid more for a strudel than a tart
= 6 u - 1 u
= 5 u
= 5 x 20
= 100¢
100¢ = $1
Answer(s): (a) 20¢ (b) $1
