Step 1: find the total exercise number or time which in this situation is 240 step 2: take 240 - 25 minutes of stretching to get 215 and divide it by 5 to get the number per day = 43 minutes a day step 3: is just recognizing the numbers (5 a day in stretching and 43 a day in running)
final step is the equation use the y intercept of 25 and the variable of running per day to get the equation of (43m + 25 = y
