zvonat [6]

Answer: Mark up percent = 20%

Step-by-step explanation:

Given: Cost price of each T-shirt = $5.00

Amount required = $450

Total students = 75

Market price for each T-shirt to raise the required amount = (Amount required ) ÷ 75

= $450 ÷ 75

= $ 6

Mark up percent = $\dfrac{\text{Market price - Cost price}}{\text{Cost price}}\times100$

$=\dfrac{6-5}{5}\times100\\\\=20\%$

Hence, Mark up percent = 20%

Usimov [2.4K]

Answer:

a) P=0.0225

b) P=0.057375

Step-by-step explanation:

From exercise we have that 15% of items produced are defective, we conclude that probabiity:

P=15/100

P=0.15

a) We calculate the probabiity that two items are defective:

P= 0.15 · 0.15

P=0.0225

b) We calculate the probabiity that two of three items are defective:

P={3}_C_{2} · 0.85 · 0.15 · 0.15

P=\frac{3!}{2!(3-2)!} · 0.019125

P=3 · 0.019125

P=0.057375
