Ryan has $16. Tommy has $5
x more than Ryan. Peter has $2
x less than Tommy.
- Find the amount of money that Peter has in terms of x.
- Find the total amount of money that the three boys have in terms of x.
- If x = 4, how much does Peter have?
(a)
Amount that Ryan has = $16
Amount that Tommy has = $(16 + 5
x)
Amount that Peter has
= 16 + 5
x - 2
x = $(16 + 3
x)
(b)
Total amount that the three boys have
= 16 + 16 + 5
x + 16 + 3
x= 16 + 16 + 16 + 5
x + 3
x = $(48 + 8
x)
(c)
Amount that Peter has
= 16 + 3
x= 16 + 3 x 4
= 16 + 12
= $28
Answer(s): (a) $(16 + 3
x) or $(3
x + 16); (b) $(48 + 8
x) or $(8
x + 48); (c) $28
