Tanya is saving for a vacation. She wants to have at least $75 for each of the 12 days of her trip. If she saves $85 each month
for 10 months, will she save enough for money?
Use the strategy of mental math to find the total amount she will save. Then write a division equation to see if she will save enough.
Jorge says he can solve this problem a different way. He says that he can compare 85 * 10 and 75 * 12. Do you agree? Explain your thinking.

Answer:
x = 3 renders the same output for both functions
Step-by-step explanation:
From the graph, we see that at the point x = 3 both lines intersect. This means that their y value coincide for that value of x.
We check using the functions' expressions to verify that our answer is correct. Then we evaluate both functions separately at x = 3:
So we conclude that effectively, the input x=3 produces equal output value (-1) for the two given functions.
