Henry's Railroad decided to use the high$-$low method and operating data from the past six months to estimate the fixed and variable components of transportation costs.

$\backslash$table$[[$Month$,$Transportation Costs,Miles$],[$January$,$$$1,500,000,350,000],[$February$,1,600,000,363,000],[$March$,1,100,000,232,000],[$April$,1,520,000,351,000],[$May$,1,300,000,283,000],[$June$,1,700,000,382,000]]$

Determine Total Fixed costs.

$$150,000$
