Sierra and Amy are selling cheesecakes for a school fundraiser. Customers can buy pecan
cheesecakes and strawberry cheesecakes. Sierra sold 10 pecan cheesecakes and 5 strawberry
cheesecakes for a total of $115. Amy sold 1 pecan cheesecake and 3 strawberry cheesecakes for a
total of $34. Find the systems of equations that best represent the situation.
1. 10p + 5s = 115
1p + 3s - 34
2. 10p + 5s = 34
1p +3s = 115
3. 5p + 10s = 115
1p + 35 = 34
4. 10p + 3s = 115
1p +55 = 34
