before swimming andrea walks for 12 minutes and burns 60 calories. While swimming she burns 10 calories per minute. Write a variable expression for how many calories Andrea burns while walking for 12 minutes and swimming for m minutes.
60 + 10m
To write a variable expression for how many calories Andrea burns while walking for 12 minutes and swimming for m minutes, we need to add the calories burned during walking to the calories burned during swimming.
The calories burned while walking for 12 minutes is given as 60 calories.
The calories burned while swimming is given as 10 calories per minute.
Since Andrea swims for m minutes, the calories burned while swimming for m minutes will be 10 * m.
Therefore, the variable expression for how many calories Andrea burns while walking for 12 minutes and swimming for m minutes is:
60 + (10 * m)
