How to solve coin word problems:
To solve these coin problems you have to add up the total value of coins in the piggy bank. You do this by multiplying the number of each coin by the value of that coin then adding the 3 values together. For example, if the piggy bank contains 7 dimes, 3 nickels, and 10 half dollars, you want to find the total of 7 dimes + 3 nickels + 10 half dollars.
Putting this into an equation you get
(7 * 0.10) + (3 * 0.05) + (10 * 0.50)
Completing the multiplication you get
0.70 + 0.15 + 5.00
And finally, adding these three values together, we find the answer to this word problem is $5.85.
