X : number of tacos they sell per day. ...... profit = y = 3.25 × x - 210 ......inequality. y > 0. so. x > 210/3.25 = 840/13 = 64. ......so the taco stand must sell at least 65 tacos for making profit.
3(41x+400) simplified = 123x+1200
72 divided by negative 9 is -8
I would say true. Hope this helps :)
