real world model for system of equations
example : you are running a food stall at a football game.you are selling hot dogs and colas .
each hotdog costs $ 1.75 and each cola costs $ 0.75
throughout the day you made a total of $ 75 ,You sold a total of 80 hotdogs and colas combined
Find out many hot dogs and how many sodas were sold ?
setting up the equations
let x = number of hotdogs sold and y = number of colas sold
x + y = 80
1.75x + .75 y = 75
solving we get
x = 15 , y = 65
so, 15 hotdogs and 65 colas were sold
