Final answer:
To find the better unit price per avocado, we compare the cost per individual avocado for each option. For Leslie's yogurt question, we convert ounces to pounds and see that a 2-pound container offers more yogurt than five 6-ounce containers.
Step-by-step explanation:
To determine which buying option has the better unit price per avocado, we need to calculate the cost per individual avocado for each option. Option 1 is 2 avocados for $3, which gives us a unit price of $rac{3}{2} = $1.50 per avocado. Without the price 'M' for the bag of 8 avocados, we cannot directly compare. However, if we have the price 'M', we calculate the unit price by dividing 'M' by 8. The option with the lower unit price is the better deal per avocado.
For Leslie's yogurt decision, she must determine which of her two options gives more yogurt for the same price of $6. First, she should convert the ounces to pounds since there are 16 ounces in 1 pound. Five 6-ounce containers equal 5 × 6 = 30 ounces, which is × 30 ÷ 16 = 1.875 pounds. Comparing that to the first option of 2 pounds, Leslie would get more yogurt with the 2-pound container, as 2 pounds is greater than 1.875 pounds.
