<human>:  Andy and Bob went to the canteen to buy snacks. They spent the same amount. Andy bought a can of soda at $1 and two hamburgers at $2 each. Bob ordered two sandwiches for $3 and a can of fruit drink. How much did Bob's fruit drink cost?
<bot>: How much did Andy's hamburgers cost? ** Two hamburger cost 2 x $2 = $<<2*2=4>>4.
How much did Andy spend? ** So, Andy spent $1 + $4 = $<<1+4=5>>5.
How much did Bob's fruit drink cost? ** Therefore, Bob's fruit drink cost $5 - $3 = $<<5-3=2>>2.
