What will be the simple interest earned when you invest $1,000 for 3 years at 10 percent and the compound interest earned when you invest the same sum for 2 years at 5 percent ? the simple interest earned when you invest $1,000 for 3 years at 10 % is $ . the interest compounded when you invest the same sum for 2 years at 5 % is $ .

simple interest = $300

compound interest =$102.5

Step-by-step explanation:

Simple interest = P* T* R

P= principal, T= time, R= rate

P= $1000,  T= 3,  R = 0.1

simple interest = 1000 * 3 *0.1 = $300

compound interest = p[(1 + r)ⁿ - 1]

compound interest = 1000[(1 + 0.05)² - 1]

                                 =  1000[1.1025 - 1]

                                   = 1000 * 0.1025

                                   = $102.5

step-by-step explanation:

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
