Answer:
Nu 4550
Step-by-step explanation:
Commission of 5% only applies to the first 70,000 so
[tex]70,000*\frac{5}{100} = 3500[/tex]
That leaves 15,000 left in sales where the 7% commission applies.
[tex]15,000*\frac{7}{100}=1050[/tex]
Adding these two together we get a total of
[tex]3500 +1050=Nu4550[/tex]
