Answer the following question, with explanation first.
Bobby has 16 toy cars, and the number of cars he has increases by 50% every year. How many toy cars will Bobby have in three years?

54
In the first year, Bobby will acquire 16 *.

5 = 8 new cars.

After the first year, he will have a total of 16 + 8 = 24 cars.

In the second year, Bobby will acquire 24 *.

5 = 12 new cars.

After the second year, he will have 24 + 12 = 36 cars in total.

In the third year, Bobby will acquire 36 *.

5 = 18 new cars.

After the third year, he will have 36 + 18 = 54 cars in total.

.

Thus, the answer is 54
