Jaslyn had an equal number of $100 and $1 notes. After spending 48 pieces of $1 and 28 pieces of $100 notes, the ratio of the $100 notes to $1 notes left was 5 : 1. Find the value of the notes left.
|
$100 |
$1 |
Before |
5 u + 28 |
1 u + 48 |
Change |
- 28 |
- 48 |
After |
5 u |
1 u |
Number of $100 notes at first = 5 u + 28
Number of $1 notes at first = 1 u + 48
The number of $100 and $1 notes at first is the same.
5 u + 28 = 1 u + 48
5 u - 1 u = 48 - 28
4 u = 20
1 u = 20 ÷ 4 = 5
Value of $100-notes left
= 5 u x 100
= 5 x 5 x 100
= $2500
Value of $1-notes left
= 1 u x 1
= 1 x 5 x 1
= $5
Value of notes left
= 2500 + 5
= $2505
Answer(s): $2505
