A barista averages making 16 coffees per hour. At this rate, how many hours will it take until she's made 1,200 coffees?

A 75 hours
Explaination
To solve the problem, simply set up a proportion using what you know and using x for what you don't know: $6404_w218_h38.png$ Cross-multiply, and you have: 16x = 1200 Divide both sides by 16 to isolate x and you have: x = 75
B 80 hours
C 65 hours
D 70 hours
