Answer:
Number of hamburgers = 120
Number of hotdogs = 180
Step-by-step explanation:
A concession stand sells hamburgers (h) for $2 and hotdogs (d) for $1.
On Friday night they sold a total of 300 hamburgers and hotdogs and made $420.
We have to find the numbers of hamburgers and hotdogs.
Now we have to form the equations
h + d = 300------(1)
2h + 1d = 420-------(2)
By subtracting equation 2 from 1.
2h + d - h - d = 420 - 300
h = 120
and from equation 1
d + 120 = 300
d = 300 - 120 = 180
Therefore total 120 hamburgers and 180 hotdogs were sold.
