One button costs $
v. One marker costs $(
v + 15). One colouring book costs $3
v.
- Fabian bought 4 buttons, 3 markers and 1 colouring book. How much did he spend? Simplify your answer in terms of v.
- If v = 17, how much did Fabian spend altogether?
(a)
Cost of 4 buttons = 4 x
v = $4
v Cost of 3 markers = 3 x (
v + 15) = $(3
v + 45)
Cost of 1 colouring book = $3
v Total amount that he spent
= 4
v + 3
v + 45 + 3
v= 4
v + 3
v + 3
v + 45
= $(10
v + 45)
(b)
If
v = 17,
total amount that he spent
= 10
v + 45
= (10 x 17) + 45
= 170 + 45
= $215
Answer(s): (a) $(10
v + 45) or $(45 + 10
v); (b) $215
