Wilson goes to a fast-food restaurant. He buys 2 hamburgers for $5 each and 3 bottles of cola for $2 each. Wilson uses his $4 discount coupon. How much money does he pay in total?
2 hamburgers cost 2*5=$<<2*5=10>>10
3 bottles of cola cost 3*2=$<<3*2=6>>6
The total price without discount is 10+6=$<<10+6=16>>16
With the discount coupon, it's 16-4=$<<16-4=12>>12
