Kim works as a sale person for a car dealership. Her base salary is $85 per day. She gets paid commission of 7.2% of anything she sells greater than $2000. Her total sale is $8230 this week. What is her gross pay for this week if she only worked 4 days?

$939.04

Step-by-step explanation:

To calculate her gross pay, we need to take into consideration, her total pay for the 4 days and her commission based on the total amount of goods she sold.

Firstly, her daily base salary is $85, since she worked for 4 days, her total salary for the four days will be $85 * 4 = $340.

Now, she is to earn 7.2% of $8,320 as commission. The amount of her commission is thus 7.2/100 * 8,320 = 599.04

Her gross pay is thus $599.04 + $340 = $939.04

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
