Dylan has a bank that sorts coins as they are dropped into it. a panel on the front displays the total number of coins inside as well as the total value of these coins. the panel shows 90 coins with a value of $17.55 inside of the bank.
if dylan only collects dimes and quarters, write a system of equations in two variables or an equation in one variable that could be used to model this situation.
using your equation or system of equations, algebraically determine the number of quarters and the number of dimes dylan has in his bank
