Question

Amber earned $14.50 babysitting on Saturday. On Sunday, she spent $6.95 when she purchased a movie ticket. She needed to borrow money from a friend to complete her purchase of a snack. How much money did Amber pay for the snack if she owes her friend $5?

Answer 1

let's let the price of the snack be x

if she owes her friend $5 after all of the purchases are done, that means the result of her earnings and spendings is -5

she earned $14.50 babysitting, spent $6.95 on the movie ticket, spent (x) dollars on the snack, and ended up with a debt of $5.

we can represent this as

14.5 - 6.95 - x = -5
can you try solving for x now?
