Answer:
- 1) 18 quarters and 30 nickels
- 2) 8 quarters and 12 nickels
Step-by-step explanation:
1) Let quarters be x and nickels be y.
<u>Equations based on given, 48 coins, total of $6 = 600c:</u>
<u>Substitute y in the second equation, y = 48 - x</u>
- 25x + 5(48 - x) = 600
- 25x + 240 - 5x = 600
- 20x = 360
- x = 18
<u>Then value of y is:</u>
2) <u>Similarly to problem 1.</u>
<u>Substitution: y= 20 - x</u>
- 25x + 5(20 - x) = 260
- 25x + 100 - 5x = 260
- 20x = 160
- x = 8
<u>Then finding y:</u>
