Answer: a. 8p b. 12p c. 84p
Step-by-step explanation:
Let the price of chews be c
Let the price of bubbly be b
3 chews and 4 bubblies cost 72p can be written as: 3c + 4b = 72
Five chew and 2 bubblies cost 64p can be written as: 5c + 2b = 64
3c + 4b = 72 ......... i
5c + 2b = 64 ........ ii
Multiply equation I by 5
Multiply equation ii by 3
15c + 20b = 360
15c + 6b = 192
Subtract
14b = 168
b = 12
Since 3c + 4b = 72
3c + 4(12) = 72
3c + 48 = 72
3c = 72 - 48
3c = 24
c = 24/3
c = 8
A chew cost 8p
A bubbly cost 12p
3 chews and 5 bubbly will cost:
(3×8) + (5×12) = 24 + 60 = 84p
