A taco truck buys 100 pounds of beef.  They use .25 pounds of beef per taco.  If they sell each taco for $2 and each taco takes $1.5 to make how much profit did they make if they used all the beef?
They made 100/.25=<<100/.25=400>>400 tacos
Each taco gives a profit of 2-1.5=$<<2-1.5=.5>>.5
So they made a profit of 400*.5=$<<400*.5=200>>200
#### 200
