Tommy has $15. Vincent has $4
j more than Tommy. Simon has $2
j less than Vincent.
- Find the amount of money that Simon has in terms of j.
- Find the total amount of money that the three boys have in terms of j.
- If j = 7, how much does Simon have?
(a)
Amount that Tommy has = $15
Amount that Vincent has = $(15 + 4
j)
Amount that Simon has
= 15 + 4
j - 2
j = $(15 + 2
j)
(b)
Total amount that the three boys have
= 15 + 15 + 4
j + 15 + 2
j= 15 + 15 + 15 + 4
j + 2
j = $(45 + 6
j)
(c)
Amount that Simon has
= 15 + 2
j= 15 + 2 x 7
= 15 + 14
= $29
Answer(s): (a) $(15 + 2
j) or $(2
j + 15); (b) $(45 + 6
j) or $(6
j + 45); (c) $29
