Three friends are starting a food truck and a contributing a total of 140,000 to begin operations. their investments are in the ratio of 2: 5: 7. what is the difference in investment betweenthe smallest investor and the largest al smallest investor and the largest inverstor

Step-by-step explanation:

The sum of those numbers is 14.  Let's divide 14000 by 14 to get the number of parts (each part will be an investment in dollars) and we get 10,000.  So if a person invests 2 parts, he invests 2(10,000).  A person that invests 5 parts invests 5(10,000), and likewise for the person investing 7 parts: 7(10,000).  That gives us 20,000 + 50,000 + 70,000 = ?  

(140,000)

The difference in investment between the largest and the smallest is 50,000
