One pen costs $
g. One notebook costs $(
g + 15). One story book costs $5
g.
- Daniel bought 4 pens, 3 notebooks and 1 story book. How much did he spend? Simplify your answer in terms of g.
- If g = 12, how much did Daniel spend altogether?
(a)
Cost of 4 pens = 4 x
g = $4
g Cost of 3 notebooks = 3 x (
g + 15) = $(3
g + 45)
Cost of 1 story book = $5
g Total amount that he spent
= 4
g + 3
g + 45 + 5
g= 4
g + 3
g + 5
g + 45
= $(12
g + 45)
(b)
If
g = 12,
total amount that he spent
= 12
g + 45
= (12 x 12) + 45
= 144 + 45
= $189
Answer(s): (a) $(12
g + 45) or $(45 + 12
g); (b) $189
