Fiona has a jar filled with 150 coins made up of quarters and nickels. The total value of the coins is $25.10. If x represents the number of quarters in the jar, which equation can be used to find the number of quarters? 0.25x + 0.05(x – 150) = 25.10 0.05x + 0.25(150 – x) = 25.10 0.05x + 0.25(x – 150) = 25.10 0.25x + 0.05(150 – x) = 25.10 is it D?
