question
Ted can clear a football field of debris in 3 hours. Jacob can clear the same field in 2 hours. When they work together, the situation can be modeled by the equation, where t is the number of hours it would take to clear the field together. 1/3+1/2=1/t How long will it take Ted and Jacob to clear the field together?

question
Megan borrowed \$50,000 at 5% simple interest for 6 years. Joseph borrowed \$60,000 at 4% simple interest for 8 years. The formula can be used to calculate the monthly payment, m, where P is the principle amount borrowed, r is the rate expressed as a decimal, and t is the amount of time for the loan, in years. Who will have a greater monthly payment, and by how much?
Megan will pay approximately \$78 more per month.
question
Max can mow a lawn in 45 minutes. Jan takes twice as long to mow the same lawn. If they work together, the situation can be modeled by the following equation, where t is the number of minutes it would take to mow the lawn together.
Max can mow a lawn: 1/45 jan can mow a lawn: 1/90 together they can mow a lawn: 1/(1/45+1/90) = 1/(1/30) = 30 min it will take them to mow the lawn.
