Each french fry costs $1.5 and hamburger $3.75
=================
- two hamburgers + two French fries = $10.50 ____ equation 1
- four hamburgers + three French fries = $19.50 _____equation 2
Consider hambugers as "h" and fench fries as "f"
- 2h + 2f = 10.5 ___ equation 1
- 4h + 3f = 19.5 ___ equation 2
We can solve them to find the cost of each hambuger and fench fry
Solve for f :
- (10.5 - 2f)/2 = (19.5 -3f)/4
Solve for h :
