Answer: D. 14
Step-by-step explanation:
Given: The base pay of salesman = $28,680
The percent of commission on each dishwasher sold = 12.5% =0.125
The cost of each dishwasher sold = $1100
Then the equation models the situation to find the total earning (y) for total cost of dishwasher (x) is given by :-
[tex]y=28680+0.125x[/tex]
Since, The base pay plus commissions of sales man= $30,605
Then ,we have
[tex]30605 =28680+12.5x\\\\\Rightarrow\ 12.5x=1925\\\\\Rightarrow x=\frac{1925}{0.125}=15400[/tex]
Since, cost of each dishwasher sold= $1100
Therefore, the number of dishwasher he sold = [tex]\frac{15400}{1100}=14[/tex]
