Julie wanted to earn money to attend a basketball camp. she started with a gift of money from her grandparents and then saved $25 per month from her dog-walking jobs. after 7 months, she had $225. which equation describes the relationship between x, the number of months julie had been saving, and y, the amount she had saved?

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.
