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 Dylan has in his bank. Dylan's mom told him that she would replace each one of his dimes with a quarter. If he uses all of his coins, determine if Dylan would then have enough money to buy a game priced at $20.98 if he must also pay an 8% sales tax. Justify your answer.
4(y-3)=3(y+6) 1) Distribute 4y-12=3y+18 2) Addition property of equality 4y=3y+30 3)Subtraction property of equality y=30 Thats your answer! Enjoy middle school while you still can!
