An ice skating arena charges an admission fee for each child plus a rental fee for each pair of ice skates. John paid the admission fees for his six nephews and rented 5 pairs of ice skates. He was charged $32.00. Juanita paid
the admission fees for her seven grandchildren and rented five pairs of ice skates. She was charged $35.25. If a
represents the amount of the admission fee and represents the skate rental fee, which of the following
systems of equations can be used to represent this situation.
A. 32.00a +5r = 5
35.25a +5r = 7
B. 5a + 6r = 32.00
5a + 7r = 35.00
C. 6a +5r = 32.00
7a +5r = 35.25
D. 8a +5r = 32.00
7a+ 7 = 35.00
