Mrs. b has $25 in her savings and wants to put $10 every week into the account. write an equation showing how much money she will have at any number of weeks. solve your equation to show the total amount of money mrs. b will have in 7 weeks. be sure to show your work.

25 + 10x = y  would be the equation because since started with 25 and wants to add 10 dollars each week, you must start with 25 and add 10 to multiply with whatever amount of weeks. 

x in this case is the amount weeks.

Now it says to indicate how much money she would have if she add 10 dollars for 7 weeks.

The equation is 25 + 10(7) = 95.

First multiply then add.

So, she would have 95 dollars in her account if she deposited 10 dollars each week.
