.00084 in scientific notation is 8.4 × 10^-4
GCF means greatest common factor and LCM means least common multiple. ;)
Answer:
You're less likely to make mistakes reading or writing very big and very small numbers if you use scientific notation. It also makes it much easier to tell at a glance which numbers are bigger or smaller without counting long strings of zeros.
If you would like to find the sales necessary for the salesperson to earn at least 800 in one week, you can calculate this using the following steps:
s ... weekly sales
350 + 10% of sales >= 800
<span>350 + 10% of s >= 800
</span>350 + 10% * s >= 800
10/100 * s >= 800 - 350
1/10 * s >= 450 /*10
s >= 450 * 10
s >= 4500
The correct result would be: <span>weekly sales >= 4500.</span>
