Answer:
$7826.78
Step-by-step explanation:
Total income = 7950
With a service fee charge of 1.55%, the service fee charge = ![1.55\%\times7950 = \dfrac{1.55}{100}\times7950 = 123.225](https://tex.z-dn.net/?f=1.55%5C%25%5Ctimes7950%20%3D%20%5Cdfrac%7B1.55%7D%7B100%7D%5Ctimes7950%20%3D%20123.225)
Net income = 7950 - 123.225 = 7826.775 = $7826.78
An alternative solution:
Service charge = 1.55%
Net income = (100 - 1.55)% × 7950
= 98.45% × 7950 = ![\dfrac{98.45}{100}\times7950 = 7826.775=7826.78](https://tex.z-dn.net/?f=%5Cdfrac%7B98.45%7D%7B100%7D%5Ctimes7950%20%3D%207826.775%3D7826.78)
