Jennifer wants to save $900 to go to Puerto Rico. She saves $45 each week and now she has $180. How many more weeks will it take to have the total amount that she needs for her trip? SOLVE THE EQUATION ALGEBRAICALLY

Respuesta :

45x+180=900
Where x is the number of weeks
45x+180-180=900-180
45x=720
X=16
It will take 16 more weeks to save the rest of the money.
