Emma has $9 more than Natalie. Vanessa has nine times as much money as Emma. They have a total of $123.
- How much money does Emma have?
- How much money does Vanessa have?
(a)
Amount that Emma has = 1 u
Amount that Natalie has = 1 u - 9
Amount that Vanessa has = 9 u
Total amount that they has
= 1 u + 1 u - 9 + 9 u
= 11 u - 9
11 u - 9 = 123
11 u = 123 + 9
11 u = 132
1 u = 132 ÷ 11 = 12
(b)
Amount that Vanessa has
= 9 u
= 9 x 12
= $108
Answer(s): (a) $12; (b) $108
