Answer: 25

Step-by-step explanation: Detailed answer:

A change from 72 to 90 represents a positive change (increase) of 25%

Use the formula found below on this webpage to find the percent change by replacing the given values:

Percent change = New - Old

|Old|

× 100%

Percent change = 90 - 72

|72|

× 100% =

18

72

× 100 = 25% (increase)

Where: 72 is the old value and 90 is the new value. In this case we have a positive change (increase) of 25 percent because the new value is greater than the old value.

Answer:

Dave worked 60 hours.

Step-by-step explanation:

Let's assume that Dave worked a total of x hours.

Since Kate worked 5 hours less than Dave: x-5

And Sarah worked 10 more hours than Dave: x+10

Combined, the three siblings worked 185 hours.

(x)+(x+10)+(x-5) = 185\\x+x+10+x-5 = 185\\3x + 5 =185\\3x = 185 - 5\\3x = 180\\x = 180 \div 3\\x = 60

Dave worked 60 hours,

Kate worked 55 hours and Sarah worked 70 hours.

To check:

55 + 60 + 70 = 185 hours
