Answer:
(a)$50
(b)$160
Explanation:
The equation that represents the charge per customer is:
[tex]\begin{gathered} y=10x+20 \\ x=\text{number of hours they go horseback riding.} \end{gathered}[/tex]Part 5
When one person goes horseback riding for 3 hours.
x=3
[tex]\begin{gathered} y=10(3)+20 \\ =30+20 \\ =\$50 \end{gathered}[/tex]Part 6
If one person goes horseback riding for 2 hours:
[tex]\begin{gathered} y=10(2)+20 \\ =20+20 \\ =\$40 \end{gathered}[/tex]Since they are a family of 4, the cost will be:
[tex]\begin{gathered} 4y=4\times40 \\ =\$160 \end{gathered}[/tex]Part 7
In the equation:
[tex]y=10x+20[/tex]The y-intercept, $20 represents the cost of entry to the ranch. It means that even if a person does not go horseback riding, they will still pay the $20.
