Step 1.1.1

Apply the distributive property.

$s = 1400 t + 1400 \cdot - 15 + 150000$

Step 1.1.2

Multiply

$1400$ by

$- 15$ .

$s = 1400 t - 21000 + 150000$

Step 1.2

Add

$- 21000$ and

$150000$ .

$s = 1400 t + 129000$

Step 2

The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.
