How to solve word problems:

To solve this problem you have to add up the total amount 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 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 multiplications you get
0.70 + 0.15 + 5.00

And finally, adding these three values together, the answer to this word problem is $5.85
