A bag contains​ pennies, nickels,​ dimes, and quarters. There are 50 coins in all. Of the​ coins, ​18% are pennies and ​36% are dimes. There are 2 more nickels than pennies. How much money does the bag​ contain?

Answers

Answer: $5.44

Step-by-step explanation:

18% of 50= 9 pennies

36% of 50= 18 dimes

9 + 2= 11 nickels

9+18+11= 38 pennies, nickels and dimes.

50 (total amount of coins) - 38 (pennies nickels and dimes)= 12 quarters.

9 pennies= 9 cents

18 dimes= 180 cents

11 nickels= 55 cents

12 quarters= 300 cents

9 + 180 + 55 + 300= 544 cents= $5.44

Answer:

$5.44

The bag contains $5.44.

Step-by-step explanation:

Pennies:

50(18/100)= 9 pennies

Dimes:

50(36/100)= 18 dimes

Nickels:

2 more nickels than pennies

9+2= 11

Quarters:

9+18+11= 38

50-38= 12 quarters

1 penny = 0.01 dollar

9x0.01= 0.09

1 dime = 0.10 dollar

18x0.10= 1.80

1 nickel = 0.05 dollar

11x0.05= 0.55

1 quarter = 0.25 dollar

12x0.25= 3

0.09+1.80+0.55+3= $5.44
