Answer:the equation would be 6x + 10x = 2050
Step-by-step explanation: to set the equation up you would fist order all of the data that is givin and after the data is organized, find out what the x varible and the y varible stand for the take the prices of the advance sales and the price at the door and put it with its varible (6x for advanced salesand 10y for the sales at the door) then add 6x to 10y = 2050 (which is the total amount of dollars made from sales) after you do all the steps you should end up with an equation that looks like this 6x + 10x = 2050
Answer:

Answer: 203.5mg and 322.5mg
Step-by-step explanation:
Let represent two serving of Mc Donald quarter pounds with = m
Let three Burger King whopper = b
given:
1). m + b = 300 + 395......equation 1.
1). m + b = 695.
And
2). 3m + b = 288.......... equation 2.
• Using Elimination method, Multiply both sides of eqn.(1) and (2)by 3. then
-3m + 3b = 2084
9m + 3b = 864
Subtract equation (1) from (2).
6m = 1221
Divide both sides by -6
m = 203.5
Substitute (m) into equation 1
3m + b = 288.
3(203.5) + b = 288.
610.5 + b = 288
b = 610.5 - 288
b = 322.5
Two servings of Mc Donald quarter pound has 203.5mg of cholesterol.
Three servings of whopper has 322.5mg of cholesterol.
