Why is the answer B?
Radda [10]

Remark

Whatever the original price, he gets 70% in the first instance.

He gets 80% in the second instance.

He gets 90% in the third instance

His total income is 240 dollars.

Let the original price be x

Equation

70%x + 80%x +90%x = 240

70% = 0.7 ; 80% = 0.8 ;90% = 0.9

Solution

0.7x + 0.8x + 0.9x = 240 Take out x as a common factor and add the decimals.

x (0.7 + 0.8 + 0.9) = 240

2.4x = 240 Divide both sides by 2.4

x = 240/2.4

x = 100

So the watches should have brought in 3*100 = 300 dollars.

He only brought in 240 dollars.

He lost 300 - 240 = 60 dollars.

The answer is B.

(Will mark brainest)If it rains tomorrow the probability is 0.6 that James will practice piano. if it doesn't rain tomorrow ther
sergiy2304 [10]

Answer:

0.64

Step-by-step explanation:

P(J / R) = P (J and R) / P(R) 

0.8 = P (J and R) / 0.6 

P (J and R) = 0.6 * 0.8 = 0.48 [Probability John practicing and it is raining] 

P(J / NR) = P (J and NR) / P(NR) 

0.4 = P (J and NR) / (1 - 0.6) = P (J and NR) / 0.4 

P (J and NR) = 0.4 * 0.4 = 0.16 [Probability John practicing and it is not raining] 

Hence; 

Probability of John practicing regardless of weather condition is 

P(John Practicing) = 0.48 + 0.16 = 0.64

HOPE THIS HELPED!!!

Pythagoras was born about 582 BC Isaac Newton was born in 1643 AD how many years apart were they born?
SSSSS [86.1K]
2225 years. Since 582 BC is 582 years away from zero and 1643 is 1643 units away from zero, you add them together. Think of it like a number line.
