Answer:
C(r) = 5 + 2.5r
Step-by-step explanation:
An amusement park charges a fee of 5$ each time you enter the park. The cost of each ride is $2.50.
Therefore, the cost of r number of rides inside the park will be $2.5r.
Hence, the expression that shows the cost C (in dollars) as a function of the number of rides r, I go on at the amusement park during one visit will be
C(r) = 5 + 2.5r (Answer)
The values of p for which the equation px = 10 have a solution −5; 1; 20 is -2, 10,
<u>Solution:</u>
Given, equation is px = 10.
We have to find the values of p for which solutions of given equations becomes -5, 1, 20.
We just need to substitute -5, 1, 20 in given equation as x, to values of p.
Now, For -5 ⇒ p(-5) = 10 ⇒ -5p = 10 ⇒ p = -2
For 1 ⇒ p(1) = 10 ⇒ p = 10
For 20 ⇒ p(20) = 10 ⇒ 20p = 10 ⇒ p =
Hence, the values of p are -2, 10, for the solutions -5, 1, 20 respectively.
3 hours and 45 minutes
The equation can be solves by adding their two efforts together in a ration equation. See below.
5/x + 15/x = 1
