I included a screenshot with the question, thank you!!

Linda loans her friend $250 with a 5% monthly intrest rate. how much was the whole loan?

Janie has $3. she earns $1.20 for each chore she does and can do fractions of chores. she wants to earn enough money to buy a cd for $13.50.

You borrow $25,000 to buy a boat. the simple interest rate is 4%. you pay the loan off after 10 years. what is the total amount you paid for the loan?
