Company A
Income = 35,000 + 0.03x

Company B
Income = 25,000 + 0.05x

set them equal to see how much of sales Julia needs to make the same income at both companies.

30,000 + 0.03x = 25,000 + 0.05x
30,000 - 25,000 = 0.05x - 0.03x
5,000 = 0.02x
5,000/0.02 = x
 250,000 = x

Company A has better base salary and so would pay better if less than 250,000 sales are made. Company B has bigger percent bonus and would be a better deal if more than 250,000 sales are made.

So it's the 2nd choice.

So, in Math I am learning Scientific Notation. Can someone show an example and some tips for me as well as the steps to remember
defon
You know how decimals are really long to write, like 0.00000000089?  Well, with scientific notation, you can shorten them.  Take the decimal I wrote for instance.  Using scientific notation, I can change it to 8.9 * 10^-10.  The decimal is shortened, and according to the exponent, 10^-10, we move the decimal place for 8.9 to the left ten places, leaving us with 0.00000000089.

‼️ IM BEING TIMED PLEASE HELP‼️<br><br> Which is the graph of fix) = 4(3)?
dexar [7]

Answer:

Step-by-step explanation:

After graphing the function f(x) = 4(\frac{1}{2})^{x}  we can see that the correct graph is the middle one in the picture. This is because with an x-input of 1 the value of 1/2 will stay the same and when multiplied by 4 it would give us a y-coordinate of 2 as seen in the middle graph. The y-coordinate keeps decreasing exponentially by half for every increase in the x-coordinate. A zoomed-in version of the graph can be seen in the attached picture below for a better understanding.
