Question 566545
Tickets for the father and son breakfast were 2 dollars for fathers and 1.50 dollars for sons. If a total of of 75 tickets were sold for 127.50 dollars, how many fathers and how many sons attended the breakfast?
---------------------------------
Equations:
f + s = 75 tickets
2f+1.5s = 127.50
---------
Multiply thru the 1st by 2 to get:
2f + 2s = 150
2f +1.5s = 127.50
-----
Subtract and solve for "s":
0.5s = 22.5
s = 45 (# of son's tickets sold)
-----
Solve for "f":
f + s = 75
f + 45 = 75
f = 30 (# of father's tickets sold)
