Robert has 12 coins totaling $1.45. None of his coins is larger than a quarter. Which of the following cannot be the number of quarters he has?

Asked by NguyetOberer

Answer (3)

The correct answer is 1 because coin • number = total value. When p = the number of pennies, n = the number of nickels, d = the number of dimes, q = the number of quarters. The total number of coins = p+ n+ d+ q = 12. But if q = 1 then p+ n+ d = 11

To find the number of quarters Robert has, set up an equation using the total value of the coins and their individual values. The maximum number of quarters Robert can have is 4 . ;

The number of quarters Robert can have in this situation is limited by the total number of coins and their value. The configurations reveal that having 1 quarter does not work with his total coins of 12 totaling $1.45. Thus, 1 cannot be the number of quarters he has.
