MATH QUESTION (PROBLEM SOLVING)

Question

Three people decide to start a business together. The cost to start the business is $10,000. They will raise the startup cost for the business by each of them investing 40% of their weekly commission (30%) from sales of their local newspaper (cost $2). If the first person sells 300 papers a week and the second person sells 500 papers a week, and the third person sells 400 papers a week, how long in weeks will it take for them to raise the $10,000?

Answer 1

0.4(0.3)(2)(300 + 500 + 400)w = 10,000

288w = 10,000

w = 34.7

35 weeks
