Oswaldo earns a salary of $2500 per month plus an 8% commission on all of his sales he wants to earn $5400 next month write an equation that shows what his total sales S must be in order for Oswaldo to reach his goal.

$2500 + 0.08 S =  $5400  is the needed equation.

In order to reach his goal, Oswaldo needs to have sales of $36,250.

Step-by-step explanation:

The monthly salary of Oswaldo = $2500

The percentage of his commission on Sales = 8%

His total goal for next month  = $5400

Now, let us assume that his TOTAL SALES in next month = $S

Calculating 8% of total sales:

8%  of S  =

So, his total commission on total sales = 0.08 S

To earn his desired amount :

Total SALARY + Amount earned from  COMMISSION = Desired Amount

⇒ $2500 + 0.08 S =  $5400

Now, solving for the value of S, we get:

0.08 S  = 5400 - 2500 = 2900

or,

⇒ S  = $36,250

Hence, in order to reach his goal, Oswaldo needs to have sales of $36,120.
