Problema Solution
On Friday, a local hamburger shop sold a combined total of 243 hamburgers and cheeseburgers. The number of cheeseburgers sold was two times the number of hamburgers sold. How many hamburgers were sold on Friday?
Answer provided by our tutors
Let
'x' be the number of hamburgers sold
'y' be the number of cheeseburgers sold
x + y = 243 (total of 243 hamburgers and cheeseburgers)
y = 2*x (number of cheeseburgers sold was two times the number of hamburgers sold)
Solve the system
y = 2*x
x + y = 243
x = 81 hamburger
y = 162 cheeseburgers
There were 81 hamburgers sold on Friday.
