Answer:
4
Step-by-step explanation:
The function is given as 5c+cd, c=1/5 and d=15d.
We evaluate by substituting the given values of c and d in the function:
[tex]5c+cd, c=1/5 \ \ \, d=15\\\\=5\times \frac{1}{5}+\frac{1}{5}\times 15[/tex]
[tex]=1++3\\\\=4[/tex]
After substituting, we find the function's equivalent as 4.
Hence, the value of the function is 4
