Alexxandr [17]

Answer:

After 4 weeks they have $413

After 5 weeks they have $485 (more than enough money)  

Step-by-step explanation:

we know that here are 3 people saving up this money and we know that they have already saved 125 dollars.

if each saves $24 per week... 24*3=72 (total profit per week)

for 4 weeks... 72*4=288

288+125(already saved up)= 413

If they go one more week and save up another 72 dollars in 1 week this will bring them past their goal
