I appreciate any help. Thank you.

1. A person went to the store to buy olives. There were two jars. Jar 1 held 21b 4 ounces and cost $7.20, Jar two had 12 ounces for $3.00. 2. A bushel of apples cost $30 where a dozen apples cost $3.49. 3. Eggs were sold in half dozen for 0.89 in full dozen for $1.79 and in 18 egg cartons for $ 2.79. 4. You can buy a pound of Hamberger for $3.49. Or 5 pounds for $22.00. 5. I bought a 10/24 gold bracelet which weighed 3 oz for $1600 if gold is $1750 an oz was a good deal? Why? 6. If I want to buy 10 acres of land for my cabin and a man offers to sale it to me for 0.10 cents a square foot what is the price? 7. I want to buy tires for my truck if I buy four, I get a discount of 20% if one tire is $225 how much would 4 costs? 8. Sterling silver is %80 percent silver. I see a set of silverware advertised 8 settings including a knife, spoon and two forks. If knives weigh 4 oz, spoons 2 oz, and forks weigh 3 oz. Silver is $23 an ounce is $900 a fair price? Why
