Answer:
$24 for 5 hours. For t hours, 9+3t
Step-by-step explanation:
1. First set up the equation.
[tex]x= $9+$3h[/tex] (we´ll let ¨h¨ represent every additional hour).
2. To find out how much she´ll have to spend after 5 hours, substitute 5 into the equation for h. Then solve.
[tex]x=9+3(5)\\x=9+15\\x=24[/tex] $24
3. Answer = $24.
Now to find the second answer.
1. Since we do not know the exact value of t, we can just leave it as t.
[tex]x=9+3t[/tex]
2. We cannot simplify this equation any further. Since this is how we find how much money for t hours, we leave it be.
