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

Answer:
4) -438.75
8) 539.68
12) 22.54
Step-by-step explanation:
Put the values in place of the corresponding variables and do the arithmetic.
__
4) 6xy = 6(-7 1/2)(9 3/4) = -6(7.5)(9.75) = -438.75
__
8) I = prt = $2442 × 0.085 × 2.6 = $539.68
__
12) I = prt = ($578)(0.0325)(1.2) = $22.54
