Question 1045739: calculators are sold for 25$ each. advertising costs are 75$ per month. Let x be the number of calculators sold. write a polynomial representing the monthly profit earned by selling x calculators

profit = revenue minus cost.
your cost is 75 dollars per month.
your revenue is 25 dollars for each calculator sold per month.
your profit is the revenue minus the cost.
let x = the number of calculators sold during the month.
your profit equation for the month would be:
profit = 25 * x - 75
25 * x is the revenue for the month.
75 is the cost for the month.
if you let y represent profit, then the equation becomes:
y = 25 * x - 75
