Answer :
Final answer:
To find out how many ounces of coffee can be bought for $3, determine the cost per ounce from the given pound cost and then divide $3 by that cost. At $0.75 per ounce, $3 can buy 4 ounces of coffee. Therefore, The correct option is a) 3.00 oz
Explanation:
To calculate how many ounces of coffee can be bought for $3 when a pound costs $12, we first need to determine the cost per ounce. We know that 1 pound is equal to 16 ounces. Therefore, if 16 ounces cost $12, we can find the cost per ounce by dividing $12 by 16 ounces.
$12 ÷ 16 ounces = $0.75 per ounce
Now, to find out how many ounces can be bought with $3, we divide $3 by the cost per ounce:
$3 ÷ $0.75 per ounce = 4 ounces
Therefore, for $3, you can purchase 4 ounces of coffee. This is slightly less than any of the given answer choices, so the closest option to the calculated amount is 3.00 oz, option (a).
