Question

Matt (180lb male) goes to a party and is served beer in a 16 oz red plastic cup. he has 3 cups of beer over a two hour period.

a. how many standard drinks did he consume?

Answer 1

Matt consumes 4 standard drinks

In United States, one standard drink contains approximately 14 g of pure alcohol. Beer contains roughly 4.5 to 5% alcohol and one standard drink of beer is approximately equal to 12 oz of beer.

Matt drinks from a plastic cup of volume 16 oz and he has three cups of beer. Therefore, the total volume V of beer consumed by Matt is given by,

`V=3*(16 oz)=48 oz`

Since the volume of standard drink of beer has a volume of 12 oz, the number of standard drinks Matt consumes is given by,

`n=(V)/(12oz) \\ =(16 oz)/(12 oz) \\ =4`

Thus, Matt consumes 4 standard drinks
