Question

If 5 ib of pasta salad serves 14 people how much pasta salad should you bring to a picnic with 49 people

Answer 1

You need to make an inequality. You know 5 pounds will serve 14 people but you don't know how much you need to serve 49 people so you need to set up the equation $\frac{5}{14} * \frac{x}{49}$ . You then cross multiply to get $14x=245$. Finally you divide 14 on both sides to get x=17.5 lbs of pasta salad
