Answer:

$0.68

Explanation:

Multiply each possible prize by its likelihood and add the results in order to obtain the expected value (Note that there is a 100% of losing 0.57 cents since that is the cost of entry):

EV = 5200*\frac{1}{8900} +2500*\frac{1}{6400} +900*\frac{1}{3900}+100*\frac{1}{2100} -0.57*1\\EV= \$0.68

The expected value of the amount won for one entry if the cost of entering is 57 cents is $0.68

kakasveta [241]

Answer:

The answer is: Projected net sales for this year are $45,254

Explanation:

The current total sales for MG Lighting are $50,000 (= 500 units x $100 per unit).

Next year their products will have a $10 increase (10%), so the unit price will be $110.

Due to the price increase, the number of units sold will decrease by 15%, to a total of 425 units.

MG Lighting total sales will be $46,750. Approximately 3.2% of the total sales will be returned (equivalent to $1,496).

MG Lighting net sales for this year should be $45,254 (= 46,750 - $1,496)
