The menu for your barbecue has been decided: burgers and wings!
you plan to spend no more than $24 for the meat. The local store sells Burger for $3.00 per pound and wings for $2.40 per pound.
write an inequality to model the purchase choices
burger is $3/ lb wings $2.40/lb
you want to spend no more than $24
b = number pounds burgerw = number pounds wings
