One marble costs $
v. One marker costs $(
v + 15). One colouring book costs $3
v.
- Bryan bought 2 marbles, 3 markers and 1 colouring book. How much did he spend? Simplify your answer in terms of v.
- If v = 16, how much did Bryan spend altogether?
(a)
Cost of 2 marbles = 2 x
v = $2
v Cost of 3 markers = 3 x (
v + 15) = $(3
v + 45)
Cost of 1 colouring book = $3
v Total amount that he spent
= 2
v + 3
v + 45 + 3
v= 2
v + 3
v + 3
v + 45
= $(8
v + 45)
(b)
If
v = 16,
total amount that he spent
= 8
v + 45
= (8 x 16) + 45
= 128 + 45
= $173
Answer(s): (a) $(8
v + 45) or $(45 + 8
v); (b) $173
