We have to evaluate the value of the expression [tex] 0.3 y + \frac{y}{z} [/tex] at y=10 and z =5
[tex] 0.3 y + \frac{y}{z} [/tex]
= [tex] (0.3 \times y) + \frac{y}{z} [/tex]
Substituting the values of y and z in the above expression,
= [tex] (0.3 \times 10) + \frac{10}{5} [/tex]
= [tex] 3 + 2 [/tex]
= 5.
So, the value of the given expression is 5.
