I am pretty sure the answer is 96
The equation would be y = 25x + 50
In order to find this equation, we need to know how much the gift from her grandparents was. To do so, we have to find out how much she's saved from dog walking.
Since she saves $25 a month for 7 months, we can find the total amount as:
25*7 = 175
Then we can subtract that from the total she has saved to find the amount for the gift.
225 - 175 = 50
Finally, we put the amount per month in the equation with the gift as the y intercept to create the equation above.

An hour is 60 minutes.
The trip to the arena + The return drive = 60 mintues.
Since the return drive is 8 minutes shorter, if you added 8 minutes it would be the same length as the trip to the arena.
The return drive + 8 minutes = The trip to the arena
Let's represent these two equations with variables.
x + r = 60
r + 8 = x
What we do now is use substitution. Since r + 8 = x, we can replace x from the first equation with r + 8.
x + r = 60
r + 8 + r = 60
2r + 8 = 60
2r = 52
r = 26
Then use r in an earlier equation to find a.
r + 8 = x
26 + 8 = x
x = 34
The answer is 12. Substitute a for 12 and b for 7 in the equation. Multiply first, then add/subtract from left to right
