Fluency Practice

A principal of 100,000 shillings earns simple interest at $10\%$ per year for 2 years. What is the total amount after 2 years?

20,000 sh, giving only the interest earned

200,000 sh, doubling the principal without computing interest

120,000 sh, adding the interest (20,000) to the principal (100,000)

10,000 sh, using only one year's worth of interest
