A bicycle manufacturing company makes a particular type of bike. Each child bike requires 4 hours to build and 4 hours to test. Each adult bike requires 6 hours to build and 4 hours to test. With the number of workers, the company is able to have up to 120 hours of building time and
100 hours of testing time for a week. If c represents child bikes and a represents adult bikes, determine which system of inequality best
explains whether the company can build 20 child bikes and 6 adult bikes in the week.

A. No, because the bike order does not meet the restrictions of 4c + 6a 3 120 and 4c + 4a 5 100

B. No, because the bike order does not meet the restrictions of 4c + 4a s 120 and 6c + 4a 5 100

C. Yes, because the bike order meets the restrictions of 4c + 6a s 120 and 4C + 4a 3 100

D. Yes, because the bike order meets the restrictions of 40 + 4a s 120 and 6c + 4a 3 100
