A local hamburger shop sold a combined total of 378 hamburgers and cheeseburgers on Wednesday. There were 72 fewer cheeseburgers sold than hamburgers. How many hamburgers were sold on Wednesday?

x+y=603

y=x+53

Step-by-step explanation:

Substitute what y equals in the second equation for y in the first equation:

x+(x+53)=603

2x+53=603

  -53    -53

2x=550

2    2

x=275 hamburgers

To solve for the number of cheeseburgers, substitute 275 for x in either equation.

y=x+53

y=275+53

y=328 cheeseburgers

To double check your work, make sure that 275+328=603 and that 328=275+53. Since both are true, you have solved for the number of hamburgers (275) and cheeseburgers (328).

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80
