n = (75 × 20) + (60 × 25)

Step-by-step explanation:

Minutes spent a day on cardio workout = 75 minutes

Minutes spent per day on strength workout = 60 minutes

Since the athlete does the cardio workout 20 days in a month, and the strength workout 25 days in the month. Therefore, the equation that could be used to find n, the total number of minutes the athlete spends working out in the month will be:

n = (75 × 20) + (60 × 25)

Therefore, the equation is:

n = (75 × 20) + (60 × 25)

Total minutes used will be:

n = (75 × 20) + (60 × 25)

n = 1500 + 1500

n = 3000 minutes

Since 60 minutes = 1 hour

n = 3000/60

n = 50 hours
