Question

Katie is buying souvenir gifts for her big family back home. She wants to buy everyone either a key chain or a magnet. The magnets are on sale for 50 cents each and the key chains cost $1 each. She must purchase at least 24 gifts but has to spend less than $20. Let x represent the number of magnets and y represent the number of key chains . A. Model the scenario with a system of inequalities..

Answer 1

Make an inequality representing both constraints.

0.5x+y<20

x+y≥24

Answer 2

Can it be 24<=0.5k+1m<=20 (k being #of key chains and m being #of magnets)
