PSLE Albert had 14 more one-dollar notes than fifty-dollar notes at first. He exchanged $400 worth of fifty-dollar notes for one-dollar notes. How many less fifty-dollar notes than one-dollar notes did Albert have after the exchange?
Number |
$1 |
$50 |
Before |
1 u + 14 |
1 u |
Change |
+ 400 |
- 8 |
After |
1 u + 14 + 400 |
1 u - 8 |
Number of fifty-dollar notes that Albert exchanged into one-dollar notes
= 400 ÷ 50
= 8
Number of one-dollar notes that Albert received from the exchange
= 400 ÷ 1
= 400
Number of less fifty-dollar notes than one-dollar notes
= 14 + 400 + 8
= 422
Answer: 422
