Party trays, which cost $14 to make not including labor, are sold for $35.00. If two people work 8 hour shifts making the trays at $7.00 per hour, how many trays must be sold to cover all costs including labor?

5.33 trays must be sold to cover all costs including labor

Step-by-step explanation:

Party trays, which cost $14.00 to make not including labor, are sold for $35.00. Profit on party trays excluding labour cost = $35 - $14 = $21 Now we will find total labor cost for making party tray for a day Total labor hours * wages per hour* No. of labors = $7 * $8*2 = $112 Therefore to find how many trays must be sold to cover all costs including labor just divide total labour cost for making party tray for a day by profit on party trays excluding labour cost. = $112/$21 = 5.33 It means 5.33 trays must be sold to cover all costs including labor.

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3

just sum

10 + 10 = 20
