Mayzie's Masks has a monthly demand of 250 masks. It costs $100 to place an order and the holding cost is 20% of the cost of a mask, which is $30. What is the total
cost?

$951

Step-by-step explanation:

EOQ = Sqroot{(2*Annual Demand*Ordering cost)/Holding cost}

= Sqroot{(2*250*12*100)/(0.2*30)}

= 317 Units Approximately

Total Holding cost = Average Inventory * Holding cost per unit

= (EOQ/2)*Holding cost per unit

= (317/2)*(0.2*30)

= $951

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.
