I only know the answer to the first : ( sorry. the answer to the first in detail ; ) is Tyler's $1,000 investment will be worth $1,240 after 6 years, invested at 4% interest rate. The problem gives the following relevant data: Principal = $1000Interest rate = 4% simple interest Term or time period = 6 years Since simple interest is given, we need to use the simple interest formula; I = P x R x T where: P is the principal, R is the interest rate, and T is the time the money will be invested. I = $1000 x 4% x 6yrsI = $1000 x 0.04 x 6I = 40 x 6I = 240 Interest earned after 6 years is $240.Total Investment = Principal + Interest x T x I = $1,000 + $240 x T x I = $1,240 the value of Tyler's investment after 6 years.
