A carnival charges $10 to enter, and $4 per ride. If you paid a total of $46, which of the following equations represents the number of rides, r, you went on at the carnival? Solve for “r” as well.

A) 10r + 4 = 46

B) 10r – 4 = 23

C) 4r + 10 = 46

D) 4r – 10 = 46

2) Based on the information and style of question above, write your own word problem and write the equation that could be used to solve the problem (think of “solving first and writing in reverse”)
