A=(r+k/3)f solve for r

R = (K/3) + (A/F)

Step-by-step explanation:

The goal is to isolate the r on one side.

The first step is to distribute the f on the right side of the equation.

a=rf+kr/3

Then, we should subtract rf from both sides

a-rf=kf/3

Next we need to subtract a from both sides

-rf=kf/3-a

Lastly, we should divide both sides by -f

r=-k/3+a/f

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
