A restaurant served 80 entrees during dinner. Of the 80 entrees, 24 were fish. The restaurant serves about 720 dinner entrees in a week. About how many of these 720 dinner entrees should the manager expect to be fish?
A.
56
B.
104
C.
192
D.
216

D

Step-by-step explanation:

We can set up a proportion because the "expected" amount should correspond to the sample amount.

, where x is the number of dinner entrees that are fish

Cross-multiply:

80 * x = 24 * 720

80x = 17280

Divide both sides by 80:

x = 17280/80 = 216

The answer is D.

Hope this helps!

D. 216

Step-by-step explanation:

Entrees : fish

80 : 24

720 : X

X/720 = 24/80

X = 720 × 24/80

X = 216

b is the final answer! : )
