Donovan has offers for two sales jobs. job a pays a base salary of $25,000 plus a 10% commission on sales. job b pays a base salary of $30,000 plus 8% commission on sales.
a. how much would donovan have to sell for the salary from job a to exceed the salary from job b?
b. if donovan routinely sells more than $500,000 in merchandise, which job would result in a higher salary?

  a.  more than $250,000

  b.  Job A

Step-by-step explanation:

a. If s represents Donovan's sales, his salary at the two jobs would have the specified relationship when ...

  25,000 + 0.10s > 30,000+0.08s

Subtracting 25000+0.08s we get ...

  0.02s > 5,000

Dividing by 0.02 gives ...

  s > 250,000

The salary from Job A will exceed that from Job B if Donovan sells more than $250,000.

b. $500,000 is more than $250,000, so the answer to part A applies.

Job A will result in a higher salary.

the final function for the graph becomes x-2=-1. before graphing you solve the equation, where x=1. then graph accordingly.   ( on the x-axis, 1 on the line will possess a vertical line.)

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
