Answer

The number of kilograms of potato purchased by the grocery shoppers is determined as $368 kg$

Introduction

The given is the price of the potatoes of $1 lb$

The objective is to determine the number of kilograms of potatoes bought by the grocery shoppers

Step 1

$1 lb of potatoes \cos t -\$ 1.75$

Total profit from the sale of potatoes $=\$1420$

Conversion factor $1\mathrm{lb}=0.4536\mathrm{Kg}$

Total 'Kg' of onions sold out is

$\Rightarrow \$1420\times \frac{1 \mathrm{b}\times 0.4536\mathrm{Kg}}{1\mathrm{lb}\times \$1.75}$

$=368\mathrm{Kg}$ (Rounding off three significant figures)
