Anthony borrows $6.50 from a friend to pay for a sandwich and drink at lunch. then he borrows $3.75 from his sister to pay a library fine. choose an equation to express anthony's total debt that day.

6.50 + 3.75 idrk sry

We are going to say that D= Debt

So let's see the information we have.
Anthony borrowed 6.50, which can also be written as -6.50 because it is being taken away. The reason it's being taken away 8s because Anthony has $0 so if he borrows 6.50 that puts him in debt. he now has $-6.50
The same thing happens when Anthony borrowed $3.75 from his sister. here is the equation you can use to show how much debt he is in.

D=-6.50+(-3.75)

To complete the equation, you combine like terms.
D=-10.25

Anthony is $10.25 in debt.

Well is there a picture
