Question

Which investment produces a $5 hourly profit for a candy shop earning $1 profit per pound of candy?

Worker at $10 per hour, producing eight pounds of candy per hour
Worker at $12 per hour, producing 16 pounds of candy per hour
Machine with $5 per hour operating cost, producing 10 pounds of candy per hour
Machine with $8 per hour operating cost, producing 14 pounds of candy per hour

Answer 1

D because there are 14 pounds of candy then that's $14 per hour and a machine costs $8 per hour to operate so $14 - $8 =$6 so you earn a profit of $6

A, loses profit
B, earns $4 profit
C, earns $5 profit
D, earns $6 profit

Answer 2

To determine which investment produces a $5 hourly profit for a candy shop, earning $1 profit per pound of candy, we have to analize each option.

1- Worker at $10 per hour, producing eight pounds of candy per hour. This option results in a $2 loss per hour, since the earnings are lower than the costs (8-10= -2).

2- Worker at $12 per hour, producing 16 pounds of candy per hour. This one results in a $4 profit, as the cost is lower than the earnings (16-12= 4).

3- Machine with $5 per hour operating cost, producing 10 pounds of candy per hour. Here we have a $5 profit, as the cost is of $5 and the earnings are of $10 (10-5= 5).

4- Machine with $8 per hour operating cost, producing 14 pounds of candy per hour . In this option, we have a $6 profit (14-8= 6).

So, the investment that produces a $5 hourly profit for a candy shop earning $1 profit per pound of candy is the third option, that is, a machine with $5 per hour operating cost, producing 10 pounds of candy per hour.
