Jack has $18. Henry has $5
x more than Jack. Neave has $2
x less than Henry.
- Find the amount of money that Neave 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 Neave have?
(a)
Amount that Jack has = $18
Amount that Henry has = $(18 + 5
x)
Amount that Neave has
= 18 + 5
x - 2
x = $(18 + 3
x)
(b)
Total amount that the three boys have
= 18 + 18 + 5
x + 18 + 3
x= 18 + 18 + 18 + 5
x + 3
x = $(54 + 8
x)
(c)
Amount that Neave has
= 18 + 3
x= 18 + 3 x 4
= 18 + 12
= $30
Answer(s): (a) $(18 + 3
x) or $(3
x + 18); (b) $(54 + 8
x) or $(8
x + 54); (c) $30
