Which of the following is the unit tests.
20lb for 16.20
26lb for 23.40
24lb for 18.72
22lb for 18.70
The lowest unit rate
16.20 / 20 = 0.81 per pound
23.40 / 26 = 0.90 per pound
Take it from here.
To identify which of the options is the unit price, you need to calculate the price per pound.
To do this, divide the total price by the weight in pounds for each option.
For example, for the first option:
Price per pound = total price / weight in pounds
= 16.20 / 20
= 0.81
Similarly, calculate the price per pound for the other options:
For the second option:
Price per pound = 23.40 / 26
= 0.90
For the third option:
Price per pound = 18.72 / 24
= 0.78
For the fourth option:
Price per pound = 18.70 / 22
= 0.85
Now you can compare the price per pound for each option to determine which one is the unit price. In this case, option 3 with a price of 0.78 per pound is the unit price.
