If i have 35% of a phones and its now $78 how much was the phone before the discount

denpristay [2]

Step-by-step explanation:

Multiply $78 by by 65/100 to determine the original price.

78 can be put over 1.

Multiply:

$\frac{78}{1} \times \frac{65}{100} = \frac{5070}{100}$

Simplify by dividing the numerator and denominator by 100:

$\frac{5070 \div 100}{100 \div 100} = \frac{50.70}{1}$

The original price was $50.70.

Two urns each contain green balls and blue balls. Urn I contains 4 green balls and 6 blue balls, and Urn II contains 6 green bal

Morgarella [4.7K]

Urn 1 = 4 green balls and 6 blue balls, a total of 10 balls
Urn 2 = 6 green balls and 2 blue balls, a total of 8 balls.

Probability of blue balls:
Urn 1 : P = 6/10
Urn 2 : P = 2/8

Probability that both balls are blue:
6/10 * 2/8 = 6*2 / 10*8 = 12/80 = 6/40 = 3/20

Answer is B. 3/20
