Answer 2

It costs $80 to buy an air conditioner. The cost to run it for 1 minute is $0.40.

Cost = $80

Run per minute = $0.40.

There's no exact time so substitute a variable for it: m

Add everything together.

`\$80+\$0.40m`

$80 is the price to buy it. $0.40 is the price to run it for one minute. m is a variable substituting the time it runs.
