Hayden has $200 and saves $40 more each week. However, every week she spends $10 on Dutch Bros coffee. If she wants to have $800 to buy a new computer, how long will it take for her to save this amount?

Respuesta :

okay, so you would use the formula 800= 200 + 30x which would equal twenty. It would twenty weeks.
Solve the equation 800=30x+200
