ipn [44]

Answer:

a. 0.58

b. 0.78

Step-by-step explanation:

a. The probability of egg come from B1 or B2

P(B1) = 3000/10000 = 0.3

P(B2) = 4000/10000 = 0.4

P(P1 ∪ B2) = 0.3 + 0.4 -(0.3)(0.4)

P(P1 ∪ B2) = 0.7 - 0.12

P(P1 ∪ B2) = 0.58

b. The probability that the market received an egg that is acceptable

P(received an egg that is acceptable) = P(B1 acceptable) + P(B2 acceptable) + P(B3 acceptable)

P(received an egg that is acceptable) = 0.80*3000 + 0.90*4000 + 0.60*3000 / 10000

P(received an egg that is acceptable) = 2400 + 3600 + 1800 / 10000

P(received an egg that is acceptable) = 7800 / 10000

P(received an egg that is acceptable) = 0.78

oee [108]

Answer:

The markup rate on each box=41%

Step-by-step explanation:

The markup rate is the additional price that a good is sold at expressed as a percentage. This can be expressed as;

R={(S-C)/C}×100

where;

R=markup rate

S=selling price

C=cost

In our case;

R=unknown

S=$20.50

C=$14.50

replacing;

R={(20.5-14.5)/14.5}×100

R=(6/14.5)×100

R=41.38% rounded off=41%

The markup rate on each box=41%
