Step-by-step explanation:

Expected loss (in millions) = EL

$EL = (300*0.25)+(800*0.25)\\EL = 275$

The expected loss is $275 million.

Step-by-step explanation:

Step 1: Define

Identify

$\displaystyle 10 = ax + bx$

Step 2: Solve for x

Factor: $\displaystyle 10 = ax + bx \rightarrow 10 = x(a + b)$
[Division Property of Equality] Divide a + b on both sides: $\displaystyle 10 = ax + bx \rightarrow x = \frac{10}{a + b}$
