Owen loves to eat hamburgers. He goes to his neighborhood grocery store to buy ground beef and buns to make hamburgers at home. He buys a package of hamburger buns for $1.29 and a package of ground beef for $5.82. He only has a $10 bill and wonders if he can buy some ketchup and mustard, too. The ketchup is $1.89, and the mustard is $2.69. He does not have to pay sales tax on food. ASAP PLS!
