Asale person's daily earnings include $115 per day plus commission equal to x percent (in decimal form) of his daily sales. a. write an equation that can be used to find the commision percentage (x), if the salesperson's daily sales are $1565 and his total earnings for hat day are $240.20. b. what percent is the salesperson's commision?

a.

b.  

Step-by-step explanation:

a. According to the information given in the exercise, you know that the sale person's daily earnings is the sum of $115 plus a commission of his daily sales.

Therefore, if his daily sales are $1,565, then his comission is given by:

Knowing that  his total earnings for that day are $240.20, you can write the following equation which can be used to find "x":

b. In order to find the commision percent (in decimal form) of the sale person's daily sales, you must solve for "x":

Multiplying it by 100, you get it in percent form:

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4

the correct answer is c
