Hot dogs costs $0.25 each and hamburgers cost $0.80 each they have a budget of $203 for the event. How many of each should the school council buy?

number of hotdogs  x
number of hamburgers  (427x)
.25x + .8(427x) = 203
times 100
25x + 80(427x) = 20300
55x + 34160 = 20300
55x = 13860
x = 252
need 252 hotdogs and 175 hamburgers
