Alex gets a new job as a salesman. he earns a monthly base salary of $5000 plus a commision of 5.25% on all sales. what must alex's total sales be in order for him to make $8,000 for the month

Respuesta :

Base salary of Alex = $5000
commission = 5.25% = 5.25/100 = 0.0525
total money he make with sales = $8000
let S is the total sales he make, then the equation becomes
$5000 + 0.0525S = $8000
0.0525S = 8000 - 5000
0.0525S = 3000
S = 3000 / 0.0525
S = 57142.8571429
if we want to confirm that our answer is right we can multiply the value of S with 0.0525 and we get $3000, and $5000 + $3000 = $8000
