Hi,

1) Amount invested at 4%: \$15,000
Amount invested at 8%: \$14,000
Interest: (4% x 15,000) + (8% x 14,000) = 600 + 1120 = \$1,720

2) Quantity of:
Dimes: 120
Quarters: 50

Face value of coins = Value of collection / 5 = 122.50 / 5 = \$24.50
120 dimes x \$0.10 + 50 quarters x \$0.25 = \$12.00 + \$12.50 = \$24.50

Hope this helps!
