One bead costs $
e. One marker costs $(
e + 15). One story book costs $3
e.
- Zane bought 4 beads, 3 markers and 1 story book. How much did he spend? Simplify your answer in terms of e.
- If e = 9, how much did Zane spend altogether?
(a)
Cost of 4 beads = 4 x
e = $4
e Cost of 3 markers = 3 x (
e + 15) = $(3
e + 45)
Cost of 1 story book = $3
e Total amount that he spent
= 4
e + 3
e + 45 + 3
e= 4
e + 3
e + 3
e + 45
= $(10
e + 45)
(b)
If
e = 9,
total amount that he spent
= 10
e + 45
= (10 x 9) + 45
= 90 + 45
= $135
Answer(s): (a) $(10
e + 45) or $(45 + 10
e); (b) $135
