Question

A taco stand sells tacos for $3.25 each. The stand's expenses for the day are $210. Write an inequality to represent the amount of tacos they need to sell per day to make a profit, and then solve the inequality.

Answer 1

Well , they are automatically 210 dollars in debt without selling any tacos...

each taco they sell....gets them 3.25 dollars closer to getting a profit

so they need AT LEAST 210 dollars to make a profit

\[3.25t \ge 210\]

where 't' is number of tacos sold

Answer 2

if they have to sell n tacos to make a profit, then 3.25*n>=210
