Aband that usually plays for 60 minutes played for 75 minutes. what was the percent of increase in the time played? a. 15% b. 20% c. 25% d. 30%

C. 25%

Step-by-step explanation:

percent change = (new number - old number)/(old number) * 100%

The new number is the increased time, 75 minutes, and the old number is the original time, 60 minutes.

percent change = (75 min - 60 min)/(60 min) * 100%

percent change = (15 min)/(60 min) * 100%

percent change = 0.25 * 100%

percent change = 25%

Since the percent change is a positive number, it is a percent increase.

The percent increase was 25%.

C. 25%

step-by-step explanation:

$42 / $14 = 3   (ratio 3: 1)

$7 x 3 = $21

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

−51

−3
