okay...it sells x number of calculators....at $25 a piece right?

this can be written as 25x

meaning 25 times however many calculators they sell

if they want a profit of at LEAST $275 .... we can set this equation...to be greater than or equal to 275

$$25x \ge 275$$

greater than or equal to 275..because they want at least that right? so they want either 275...or above...so greater that or equal to

now solve for x
