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?

answer

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.

answer

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.
