(a)
Cost of 1 macaron = 1 u
Cost of 1 strudel = 3 u
Cost of 6 macarons
= 6 x 1 u
= 6 u
Cost of 8 strudels
= 8 x 3 u
= 24 u
Total cost of 6 macarons and 8 strudels
= 6 u + 24 u
= 30 u
$1 = 100¢
$24 = 24 x 100 = 2400¢
30 u = 2400
1 u = 2400 ÷ 30 = 80
Cost of a bun
= 1 u
= 80¢
(b)
Amount that Xandra paid more for a strudel than a macaron
= 6 u - 1 u
= 5 u
= 5 x 80
= 400¢
400¢ = $4
Answer(s): (a) 80¢ (b) $4
