At the hot dog stand, it costs 18.39 for five hotdogs and six bags of chips. If it costs 4.63 for one hot dog and two bags of chips, how much is a hotdog?
let hotdog be h and bag of chip be c
Then:
\(5h+6c=18.39\) (1)
\(h+2c=4.63\) (2)
System of two equations.
(2) multiply by -3 and add to (1)
\(2h=4.5\)
\(h=2.25\)
