If Jack sells 120 bacon cheeseburgers total, about how many pounds of onion rings will he serve with them? (round to nearest whole number)At a mall food court, the first 40 orders for the day are given below. • 22 pizza slices • 8 hamburgers • 4 hot dogs • 6 fried chicken Based on this information, how many hamburger orders could be expected from 300 customers?

Answer 1

The correct answers are:

60 pounds of onion rings and 60 hamburgers.

Explanation:

Jack serves a half pound of onion rings with every burger.  He serves 120 bacon cheeseburgers.  To find the number of pounds of onion rings, we multiply 1/2 pound by 120 burgers:

1/2(120) = 1/2(120/1) = (1*120)/(2*1) = 120/2 = 60 pounds of onion rings.

There were 8 hamburgers served out of the first 40 orders.  If this rate continues, then to find the number of hamburgers out of 300 orders, we multiply 8/40 by 300:

8/40(300) = 8/40(300/1) = (8*300)/(40*1) = 2400/40 = 60

There would be 60 hamburgers.

Answer 2

Question:   At Best Burgers, Jack collected sales data on the type of side order served with each type of burger purchased for a week.  

Jack serves a half pound of onion rings with every kind of burger.  

If Jack sells 120 bacon cheeseburgers total, about how many pounds of onion rings will he serve with them? (round to nearest whole number)

Answer:    The answer is C) 30 pounds

Step by step explanation:

Bacon cheeseburger with onion rings:  

$\frac{40}{(41 + 40)} = \frac{40}{81} = 0.4938$

after that,  120 x 0.4938 = 59.256

then,  59.256 x .50 = 29.628

So 29.628 rounded is 30 and that is C
