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
