Question

Amanda is choosing between two exercise routines.

Answer 1

Amanda needs to spend more than 8 minutes on Routine 1 to burn more calories.

Step-by-step explanation:

Given,

Calories burned in Routine 1 = 15.5 calories per minute

Let,

t represents the number of minutes spent running.

Total calories burned = T

T = 15.5t   Eqn 1

Calories burned in Routine 2 = 22 calories walking + 12.75 per minute

T = 12.75t + 22    Eqn 2

For burning more calories in Routine 1;

Eqn 1 > Eqn 2

$15.5t>12.75t+22\\15.5t-12.75>22\\2.75t>22$

Dividing both sides by 2.75

$\frac{2.75t}{2.75}>\frac{22}{2.75}\\t>8$

Amanda needs to spend more than 8 minutes on Routine 1 to burn more calories.
