Alexander is going to an amusment park . The price of admission into the park is $15,and once he is i side the park, he will have to pay$3 for every ride he rides on. How much money would Alexander have to pay in total if he goes on 5 rides? How much would he have to pay if he goes on r rides?

For r rides, amount paid will be $(r + 15)

For 5 rides, amount paid will be $30

Step-by-step explanation:

Here, we want to know the total amount to be paid

We should note that $15 admission fee is fixed

Now for 5 rides, at $3 per ride, the amount paid to ride will be 3 * 5 = $15

Total amount paid will be $15 + $15 = $30

If it’s r rides

Total amount will be;

15 + r(3)

3r + 15

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
