Mary is trying to raise 150 dollars to buy a new pair of ugg boots . she was given $25 for her birthday. she makes 25 dollars
every time she babysits her neighbor's kid . how many days must she babysit ? write an equation to represent this situation and solve

Here is a esay way 150$ - 25$ 
=> 125$ / 25
=> 25$ x 5$
=> 125$
She Must baby sit 5 days  to buy the boots

So this is pretty simple. So we know that Mary tries to raise 150 dollars. We also know that she already has $25. Also Mary gets paid 25 dollars every time she babysits. So we know that we have to multiply for $25 times d. So it's our job to find out how many times she babysits. Then you have to add up what she already has which is $25. So put that together 25xd then add that answer by 25 and BOOM there you go..

If your having trouble the answer is d=5. So multiply 25 x 5 then add.
