One card costs $
v. One notebook costs $(
v + 15). One guide book costs $5
v.
- Bryan bought 6 cards, 3 notebooks and 1 guide book. How much did he spend? Simplify your answer in terms of v.
- If v = 19, how much did Bryan spend altogether?
(a)
Cost of 6 cards = 6 x
v = $6
v Cost of 3 notebooks = 3 x (
v + 15) = $(3
v + 45)
Cost of 1 guide book = $5
v Total amount that he spent
= 6
v + 3
v + 45 + 5
v= 6
v + 3
v + 5
v + 45
= $(14
v + 45)
(b)
If
v = 19,
total amount that he spent
= 14
v + 45
= (14 x 19) + 45
= 266 + 45
= $311
Answer(s): (a) $(14
v + 45) or $(45 + 14
v); (b) $311
