Answer:
She went on the slide 8 times and on the roller coaster 4 times
Step-by-step explanation:
We convert each statements to a mathematical equation.
Firstly, let's represent the number of times she went on the coaster with R and the number of times on the slide with S. We know quite well she went on 12 rides. Hence the summation of both number of times yield 12.
Mathematically, R + S = 12. ........(i)
Now we also know her total wait time was 3hours. Since an hour equals 60 minutes, her total wait time would equal 180 minutes.
To get a mathematical representation for the wait time, we multiply the number of roller coaster rides by 25 and that of the slides by 10.
Mathematically, 25R + 10S = 180 .......(ii)
Here we now have two equations that we can solve simultaneously.
From equation 1 we can say R = 12 - S. We can then substitute this into equation 2 to yield the following:
25(12 - s) + 10s = 180
300 - 25s + 10s = 180
300 - 25s + 10s = 180
300 - 15s = 180
15s = 300 - 180
15s = 120
S = 120/15
S = 8
S = 8 , and R = 12 - S = 12 - 8 = 4

Answer:
i struggle with this to sry and hey
Step-by-step explanation:
<u>Answer:</u>
Lamar will charge
to the comic dealer for a comic book.
<u>Solution:</u>
It is given that lamar purchases a comic book for 
. He then marks up the price of a comic book by 
which means he increases the price of the book by and then sells it to the comic dealer.
We have to find out how much will he charge the comic book dealer.
New price of the book after lamar marks up the price is given by
New price 
=
Thus, lamar will charge to the comic dealer for a comic book.
