One button costs $
h. One stapler costs $(
h + 15). One story book costs $4
h.
- Valen bought 6 buttons, 3 staplers and 1 story book. How much did he spend? Simplify your answer in terms of h.
- If h = 11, how much did Valen spend altogether?
(a)
Cost of 6 buttons = 6 x
h = $6
h Cost of 3 staplers = 3 x (
h + 15) = $(3
h + 45)
Cost of 1 story book = $4
h Total amount that he spent
= 6
h + 3
h + 45 + 4
h= 6
h + 3
h + 4
h + 45
= $(13
h + 45)
(b)
If
h = 11,
total amount that he spent
= 13
h + 45
= (13 x 11) + 45
= 143 + 45
= $188
Answer(s): (a) $(13
h + 45) or $(45 + 13
h); (b) $188
