John drinks 2 energy drinks. 1 of them is a 12-ounce drink with 250 grams of caffeine.  The second drink is 3 times more caffeinated per ounce but only 2 ounces.  He then takes a caffeine pill that has as much caffeine as his 2 drinks combined.  How much caffeine did he consume?
The second drink was 2/12=1/6 the size of the first drink.
So it had 1/6*3=1/2 the caffeine.
That means it had 1/2*250=

<output>125</output>
125 grams of caffeine.
So the total amount of caffeine he drank was 125+250=

<output>375</output>
375 grams.
So he consumed 375*2=
