Question

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.

Answer 1

No, because the bike order does not meet the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100

No, because the bike order does not meet the restrictions of 4c + 4a ≤ 120 and 6c + 4a ≤ 100

Yes, because the bike order meets the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100

Yes, because the bike order meets the restrictions of 4c + 4a ≤ 120 and 6c + 4a ≤ 100

Answer 2

Hi sara lee rather than going through each answer, let's try to see if we can get an answer similar to the ones given.

So what we know is that it takes 4 hours to build a child's bike and 4 hours to test the bike. If we have c amount of bike. How would we represent how many hours it would take to build all of those bikes?

Answer 3

Would it be C?

Answer 4

honestly I can't tell you because the answers you provided don't come out correctly.

Answer 5

All I see are long stretches of question marks

Answer 6

but from what I can see I can actually tell you that it isn't C.

Answer 7

Oh... HOw about B?

Answer 8

hmm rather than guessing...why don't you tell me how you solved the problem?

Answer 9

btw I can see the answers now.

Answer 10

Well, I already got it! Thank you

Answer 11

I see. Well that's good.
