Answer 2

Shoppers bought 368 kilograms of grocery

Given - Price of 1 lb of potatoes.

Find - Number of kilograms of potatoes

Solution - This question will be solved in two steps. Firstly we will solve the question using unitary method. This will give us the answer of amount of potatoes. Further, we will convert the units to get final answer.

$1.75 is the cost of amount of potatoes = 1 lb

So, $1420 will be the cost of amount of potatoes = (1÷1.75)×1420

Amount of potatoes = 0.57×1420

Performing multiplication

Amount of potatoes = 811.4 lbs

Now, as per the known fact -

1 lb = 0.454 kilogram

So, 811.4 lbs will be equal to number of kilograms = 368 kilograms

Hence, shoppers bought 368 kilograms of grocery.
