    Answer:

    $4.98

    Step-by-step explanation:

    50*16%=8 (pennies), 50*40%=20 (dimes)

    8+5=13 (nickels), 50-(8+20+13)=9 (quarters)

    So the money in total is 8*0.01+20*0.1+13*0.05+9*0.25=$4.98

    ANSWER: $4.98

    Steps for pennies:

    1.) 50 * .16 = 8

    8 pennies out of 50 coins

    2.) 1 cent * 8 = 8 cents

    Steps for dimes:

    1.) 50 * .40 = 20

    20 dimes out of 50 coins

    2.) 10 cents * 20 = 200 cents = $2

    Steps for nickels:

    1.) 8 + 5 = 13

    13 nickels out of 50 coins

    2.) 5 cents * 13 = 65 cents

    Steps for quarters:

    1. 8 + 20 + 13 = 41

    2. 50 – 41 = 9

    3. 9 * .25 = $2.25

    FINAL STEP:

    8 cents + $2 + 65 cents + $2.25 = $4.98

    ANSWER: the bag contained $4.98

    *to change a percentage into a decimal move the decimal point 2 places to the left. Ex.) 50% > 50. > .50

    50% = .50
