The equation that represents profit is $40x - $20.
The profit after 5 days in business is $180.
The profit after 10 days in business is $380.
The profit after 10 days in business if revenue is $45 is $430.
<h3>What is profit? </h3>
Profit is total revenue less total cost.
Profit = total revenue - total cost
Profit = $40x - $20
Where:
x = number of days
<h3>What is the total profit after 5 days and 10 days? </h3>
$40(5) - $20
= $200 - $20
= $180
$40(10) - $20
$400 - $20
$380
<h3>What is total profit if revenue is $45? </h3>
$45(10) - $20
= $450 - $20
= $430
