A bag contains pennies, nickels, dimes and quarters. There are 50 coins in all. Of the coins, 8% are pennies and 30% are dimes. There are 10 more nickels than pennies. How much money does the bag contain?

$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

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality
