Roshel had an equal number of $2 and $100 notes. After spending 18 pieces of $100 and 14 pieces of $2 notes, the ratio of the $2 notes to $100 notes left was 5 : 1. Find the value of the notes left.
|
$2 |
$100 |
Before |
5 u + 14 |
1 u + 18 |
Change |
- 14 |
- 18 |
After |
5 u |
1 u |
Number of $2 notes at first = 5 u + 14
Number of $100 notes at first = 1 u + 18
The number of $2 and $100 notes at first is the same.
5 u + 14 = 1 u + 18
5 u - 1 u = 18 - 14
4 u = 4
1 u = 4 ÷ 4 = 1
Value of $2-notes left
= 5 u x 2
= 5 x 1 x 2
= $10
Value of $100-notes left
= 1 u x 100
= 1 x 1 x 100
= $100
Value of notes left
= 10 + 100
= $110
Answer(s): $110
