David has $14. Oscar has $5
y more than David. Howard has $2
y less than Oscar.
- Find the amount of money that Howard has in terms of y.
- Find the total amount of money that the three boys have in terms of y.
- If y = 4, how much does Howard have?
(a)
Amount that David has = $14
Amount that Oscar has = $(14 + 5
y)
Amount that Howard has
= 14 + 5
y - 2
y = $(14 + 3
y)
(b)
Total amount that the three boys have
= 14 + 14 + 5
y + 14 + 3
y= 14 + 14 + 14 + 5
y + 3
y = $(42 + 8
y)
(c)
Amount that Howard has
= 14 + 3
y= 14 + 3 x 4
= 14 + 12
= $26
Answer(s): (a) $(14 + 3
y) or $(3
y + 14); (b) $(42 + 8
y) or $(8
y + 42); (c) $26
