Question

The formula Total cost = Cost + Shipping cost + Installation is used to find the total cost of a business asset. The formula can be written in symbols as T=C+S+I. Solve theformula for I, the installation cost of the asset.1=(Simplify your answer.)

Answer 1

We have the next formula for the total cost:

$T=C+S+I$

Now, we need to isolate the I variable

First, subtract both sides c

$T-C=C-C+S+I$$T-C=S+I$

Now, subtract both sides S:

$T-C-S=S-S+I$

Therefore:

$I=T-C-S$
