Acompany that sells widgets has to pay $\$500$ in maintenance fees each day and then it pays each worker $\$15$ per hour. each worker makes 5 widgets per hour, which are sold at $\$3.10$ each. what is the least number of workers the company has to hire in order to make a profit in an 8-hour workday?

Let's use h to represent h for hours:

500 + 15r > 5*3.10h

15r + 500 > 15.5h

0.5h > 500

h > 1000

So, one person needs at least 1000 hours to make profit, so now we need to divide by 8:

1000/8 = 125

The least amount of people required is 125 people.

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
