You have a piggy bank containing a total of 119 coins in dimes and quarters. If the piggy bank contains $20.75, how many dimes are there in the piggy bank

Let the number of dimes = xLet the number of quarters = y You know that each dime is worth $0.10You know that each quarter is worth $0.25 Using the variables above, we can write two equations that represents the total number of coins and total amount. x + y = 47 eq10.10x + 0.25y = 8 eq2 You can use the substitution/elimination method to solve for x and y. 3/6/2017 | Michael J.
