Question

You have $100 to spend on a bbq where you want to serve chicken and steak. Chicken costs $1.29 per pound and steak costs $3.49 per pound.
Write the function that relates the amount of chicken and steak you are able to buy.

Answer 1

$100=1.29c+3.49s. c is for chicken, s for steak

Answer 2

3.49s+1.29c=100
C is standing for chicken while s is standing for steak. Since the values are per pound, you just have to multiply it. Finally, all you have is 100 so you have a limit.
