Answer:
Graph 3
Step-by-step explanation:
Given : Jamal earns $7 an hour Helping his neighbors.
He wants to earn more than $105 altogether.
He has already earned $63.
To Find: Which graph shows the remaining number of hours Jamall could work to earn more than $105?
Solution:
Let x be the number of the remaining number of hours Jamal could work to earn more than $105.
He earns in 1 hour = $7
He earns ion x hours = $7x
He already has money = $63
He wants to earn more than $105 altogether
So, equation becomes : [tex]63+7x\geq 105[/tex]
[tex]7x\geq 105-63[/tex]
[tex]7x\geq 42[/tex]
[tex]x\geq \frac{42}{7}[/tex]
[tex]x\geq 6[/tex]
Thus the remaining number of hours Jamal could work to earn more than $105 must be 6 or more than 6 hours .
Since 6 is included . So, Graph 3 is correct.
Hence Graph 3 shows the remaining number of hours Jamal could work to earn more than $105 must be 6 or more than 6 hours.
