Answer:
$6.49
Step-by-step explanation:
Pennies = 8% of 50 =4 ; 4x0.01 = 0.04
Dimes = 30% of 50 = 15 ; 15x0.10 = 1.50
Nickels = 10 + 4(number of pennies) = 14; 14x 0.05 =0.70
Quarters = 50 - 33 (total pennies + dimes + nickels ) = 17 ; 17x0.25=4.25
Therefore total amount in bag = 0.04+1.50+0.70+4.25 = $6.49
The total amount of money they collected for the charity is 29.1 pounds
<h3>How to find the total amount they collected?</h3>
100 pence = 1 pounds
Hence,
52 twenty pence coins = 1040 pence = 1040 / 100 = 10.4 pounds
59 ten pence coins = 590 pence = 590 / 100 = 5.9 pounds
26 five pence coins = 130 pence = 1.3 pounds
5 fifty pence coins = 250 pence = 2.5 pounds
9 £1 coins = 9 pounds
Therefore,
The amount of money collected = 10.4 + 5.9 + 1.3 + 2.5 + 9 = 29.1 pounds
