Question: Find a solution for this math problem: James likes to check the coin return of the vending machine for change. One day he finds a quarter, two nickels, and 7 dimes. How much money in cents does James have?
Answer: 
First figure out how much the nickels are worth: 2 * 5 cents = 10 cents
Then figure out how much the dimes are worth: 7 * 10 cents = 70 cents
Finally, add the value of the nickels, dimes and quarter: 25 cents + 10 cents + 70 cents = 105 cents
