You can multiply both sides by a number that will get rid of the denominators. For ex. you can multiply the first equation by 12 because 4 and 3 both go into 12 evenly. MAKE SURE YOU MULTIPLY THE OTHER SIDE BY 12 AS WELL! Therefore, 12(x/4) - 12(y/3) = 12(1), or 3x - 4y = 12

Answer:

ticket cost = 37.23

Equation:- $930.75 = 25F

Step-by-step explanation:

$930.75 = 25F

F being the variable, representing the ticket cost

The total amount is equal to the number of seat per ticket

Part B:- 930.75/ 25 = 25F/25

300 cookies were ordered to start. 

We can tell this because we know 12% is equal to 36. Because this is true, we can set up a proportion to solve. All proportions can be set up with the small number on top and the total on the bottom. This will help you solve for the missing number, which is in this case the total number of cookies.  Let x be the total number of cookies.  

Percentage/total percentage = cookies/cookies total 
12/100 = 36/x

Now we can cross multiply to solve. 
(100)(36) = (12)(x) ----> multiply 
3600 = 12x ---> divide by 12
300 = x
