Answer: $5.63
Step-by-step explanation:
The first thing you want to do is calculate the amount of pennies and dimes from the total and the percent given: 16% of 50 is 8 and 34% of 50 is 17. From this information, there are 12 nickles since 8 + 4 = 12. Here, it does not give enough information to go further. If we assume that the last 13 coins are quarters (though even if we are only talking about U.S. coins, there still are half-dollar and dollar coins), then we can reach the 50 coin amount this way. If we multiply each amount of coins by their value and add them all up, 8*0.01 + 12*0.05 + 17*0.10 + 13*0.25, we will get $5.63.
