Selena is 6 years younger than Paul. In 15 years, Paul will be 4 times the age that Selena is now. Find their present ages.
s344n2d4d5 [400]

Answer:

<u>The ages of Paul and Selena are 13 and 7 years old.</u>

Step-by-step explanation:

Age of Paul = x

Age of Selena = x -6

Age of Paul and Selena in 15 years:

x + 15 = 4 (x - 6)

x + 15 = 4x - 24

x - 4x = -24 - 15

- 3x = -39

x = 13

<u>Paul now is 13 years old and Selena is 7 years old. In 15 years, Paul will be 28, that is 4 times the present age of Selena.</u>

Tom works for a company his normal rate of pay 15 per hour
Brrunno [24]

The amount earned by Tom is the product of the <em>rate per</em> <em>hour and the number of hours</em> worked which is $90.

  • The amount earned per hour = $15

  • The number of hours worked = 6 hours

<u>The amount earned at the normal earning rate can be calculated thus</u> :

  • <em>Normal rate per hour × number of hours</em>

Amount earned = $15 × 6 = $90

Therefore, the amount earned by Tom after working for 6 hours at the normal rate is $90.
