B.. $60
C.. $154
D.. $42

Answer 1

After 11 trips on the toll roads, Aldo has $70 left in his toll road account.

Step-by-step explanation:

To determine how much money Aldo has left in his toll road account after 11 trips, we need to plug in the number of trips into the function A(I) = 224 - 14I. Substituting 11 for I gives us A(11) = 224 - 14(11). Calculating further, we get A(11) = 224 - 154, which simplifies to A(11) = $70. Therefore, Aldo has $70 left in his toll road account after 11 trips.
