Goshia [24]

Answer:

Soleil and Malvin would have $ 5,000 all together after 13 days.

Step-by-step explanation:

Since Soleil and Malvin each work a job, and Soleil starts with $ 700 and makes $ 100 per day while Malvin starts out with $ 200 and makes $ 120 per day, to determine after how many days will they have at least $ 5000 all together it must be done the following calculation:

5,000 - 700 - 200 = 4,100

200X + 120X = 4,100

320X = 4,100

X = 4,100 / 320

X = 12.8

So Soleil and Malvin would have $ 5,000 all together after 13 days.
