Question 198041: While training for soccer you work out each day after school. During your workout you lift weights and play soccer for a total of 75 minutes. You burn 7 calories per minute when playing soccer and 3 calories per minute when lifting weights. If t is minutes you play soccer write an expression in terms of t for the total calories you burn during your workout. Then find the total number of calories burned if you play soccer for 55 minutes.
Is this right: 75= 7+3+t
75= 10+t
65= t(total calories burned
then you would do 75= 7+3+55t
75= 10+55t
