Answer:
1. [tex]16\ onions[/tex]
2. [tex]4,040.91\ kg[/tex]
Step-by-step explanation:
1. You know that the average mass of an onion is 115 grams and Bill needs 4.0 pounds.
Then, since [tex]1\ lb=453.592\ g[/tex], we can make the following conversion:
[tex](4.0\ lb)(\frac{453.592\ g}{1\ lb})=1,814.37\ g[/tex]
Then, the number of onions Bill needs is:
[tex](1,814.37\ g)(\frac{1\ onion}{115\ g})=15.77\ onions[/tex] ≈ [tex]16\ onions[/tex]
2. Since [tex]1\ kg=2.20462\ lb[/tex], we can make the following conversion:
[tex](11\ lb)(\frac{1\ kg}{2.20462\ lb})=4.98\ kg[/tex]
Knowing that all the potatoes sold today at the store bring in $1,420 and 4.98 kilograms of potatoes is $1.75, we can calculate the amount of kilograms the grocery shoppers bought:
[tex](\$1,420)(\frac{4.98\ kg}{\$1.75})=4,040.91\ kg[/tex]
