Answer:
- 7 quarters, 14 dimes, 7 nickels total $3.50
- $0.80 will remain
Step-by-step explanation:
a) 1/4 of 28 = 28/4 = 7 coins are quarters.
2/3 of (28 -7) = (2/3)(21) = 14 coins are dimes
The remaining 28 -7 -14 = 7 coins are nickels

b) The amount of money in coins is ...
7×$0.25 +14×$0.10 +7×$0.05 = $3.50 . . . in coins

c) 2 packs of cards at $1.35 each will cost 2×$1.35 = $2.70. After the purchase, the remaining money would be ...
$3.50 -2.70 = $0.80 . . . remaining
First you have to find 20% of $8. you have to convert 20% into a decimal and multiply that by 8 which would be 1.6. then, add that to the $8. your answer would be $9.60.
