so, her trip costs 800 dollars. she earns 125 a month, but spends 20 bucks each month. we need to make an equation which will be 125x-20=800, x being the amount of months it will take for her to get 800 bucks. Then, solve for x. Add 20 on each sides of the equation, resulting in 125x = 800 +20. Then, solve for x. The answer would be 8 months because 125 multiplied by 8 equals 1000 and minus her 20 dollar expenses would be 800.

You would take the $20 dollars out because she uses it for personal use and then I think you would divide 105 by 800 since she saves $105 each month and gets roughly 7.6 months to save up
