Answer 1

Answer: About $300

Step-by-step explanation:

1. To solve this problem and estimate how much more money Mr. Johnson made this week (which you can call x) you must apply the proccedure shown below:

- Round the number of erasers sold:

96 erasers≈100 erasers

204 erasers≈200 erasers

- The amount of money made last week is:

$\ 3*100=300$

- The amount of money made this week is:

$\ 3*200=600$

- Now, you must subtract the quantities shown above, then you obtain:

$m=\ 600-\ 300\\m=\ 300$
