1. Sandra just opened up her own pie shop. She makes $38 on every pie that. she sells and her monthly expenses are $850. How many pies does Sandra nded to
sell this month so that she can earn a total of $100 after she pays her monthly
expenses?

25

Step-by-step explanation:

If you take the 100+850= 950 then you take that because that is the expenses and what she wants to make you will then divide 950/38=25 so sandra will need to sell 25 pie in order to cover the monthly cost and what she wants to earn.

25 pies

850 + 100 = $950

So Sandra needs $950 in total.

If you divide 950 by 38 (how much a pie costs) then you get 25.

hope this helps :)
