A supermarket buys lettuce each day from its supplier. Each morning any lettuce that is left from the previous day is sold to a
Step2247 [10]

Answer:

The number of boxes of lettuce the supermarket should purchase = 273 boxes

Step-by-step explanation:

This is a case of understocking and overstocking.

We are given;

Cost price = $4 per box

Selling price = $10 per box

Salvage value = $2

The formula for cost of understocking is;

C_u = S.P - C.P

Where;

C_u is cost of understocking

S.P is selling price

C.P is cost price

Thus;

C_u = $10 - $4

C_u = $6

Cost of overstocking is given by;

C_o = Cost Price - Salvage value

C_o = $4 - $2

C_o = $2

Now,

P(D ≤ Q) = C_u/(C_u + C_o)

P(D ≤ Q) = 6/(6 + 2) = 6/8 = 0.75

From the z-table i attached, the z value of 0.75 is approximately 0.67

Thus;

The number of boxes of lettuce the supermarket should purchase =

D + (z-value x standard deviation)

We are given;

D = 250

Standard deviation = 34

Thus;

The number of boxes of lettuce the supermarket should purchase = 250 + (0.67 * 34) = 272.78 ≈ 273 boxes

How to find the height of a triangle<br> Base: 36<br> Area:558
bija089 [108]
You know that the area of a triangle is (h*b)/2
if we know the area  we will have 558= (h* 36)/2
or  558*2= h*36
h=(558*2)/36=31
h=31
