Question

HELP PLEASE

Answer 1

Answer:

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

Step-by-step explanation:

The correct answer is option 1:

$4c+6a \leq 120$ (As each child bike takes 4 hours to build and each adult bike takes 6 hours to build, and the company has building time up to 120 hours)

$4c +4a\leq 100$ (As each child bike takes 4 hours to test and each adult bike takes 4 hours to test, and the company has testing time up to 100 hours)

We will substitute 20 for 'c' and 6 for 'a'

$4(20)+6(6) \leq 120$

$80+36 \leq 120$

$116 \leq 120$

This is true.

For the second inequality;

$4(20)+4(6) \leq 100$

$80+24 \leq 100$

$104 \leq 100$

So, this is not true.

Hence, option 1st is true.
