Answer 1

The correct answer is 94 i took the test and it was right

Explanation:

Answer 2

To answer this question, substitute the number of tickets sold for the x value.

y = 3.4(15) + 43

Solve the equation by first multiplying the 3.4 and the 15.

3.4 x 15 = 51

This leaves your equation looking like this:

y = 51 + 43

The final step is to add he two integers together.

51 + 43 = 94

So the final answer is y = 94
