TCP=35.5*1.6
TCP=284/5
Generally, the equation for is Total selling price mathematically given as
TSP=89.99+7.99
TSP=97.98
In conclusion, Mark up percentage is
![M=\frac{SP-CP}{SP}*100\\\\](https://tex.z-dn.net/?f=M%3D%5Cfrac%7BSP-CP%7D%7BSP%7D%2A100%5C%5C%5C%5C)
![M= \frac {97.98 - (284/5) }{97.98} *100](https://tex.z-dn.net/?f=M%3D%20%5Cfrac%20%7B97.98%20-%20%28284%2F5%29%20%7D%7B97.98%7D%20%20%20%2A100)
M=0.4202898551*100
M=42%
