Question

Tony earns $7 and saves $2. When he earns $10, he saves $5. When he earns $49, he saves $44. Write an expression for the amount Tony saves each time he earns money.

Answer 1

Answer: you subtract 5 every time

because 7-5=2

10-5=5

and 49-5=44

so the expression would be any letter

so y-5

Answer 2

2= 7-x
5= 10-x
44= 49-x
I think this is what you mean
