Answer:

26 = G. 27 = A. 28 = J

Step-by-step explanation:

26} A Nickle = 5 cents. A Dime = 10 Cents.

Way #1: 5+5+5+5+5+5 = 30

Way #2: 10 + 10 + 10 = 30

Way #3: 10 + 5 + 5 + 5 + 5 = 30

Way #4: 10+ 10+ 5 + 5 = 30

27} Pennies = 1 Cent. Nickels = 5 Cents. Dimes = 10 cents.

Way #1: 1+1+1+1+1+5+ 10 = 20

28} Pennies = 1 Cent. Nickels = 5 Cents. Dimes = 10 Cents.

Way #1: 10+5+1+1 = 17

Way #2: 5+5+5+11 = 17

Way #3: 1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1 = 17

Way #4: 1+1+1+1+1+1+1+10 = 17

Way #5: 5+1+1+1+1+1+1+1+1+1+1+1+1 = 17
