Jorden Hudson · Answer 1

Step-by-step explanation:

Use the simple interest formula, P * r * t = I, to solve. P is the initial investment, r is the rate in decimal form, t is the time in years, and I is the interest earned. Filling in what we have:

8000 (r) (10) = 3000 and

80000r = 3000 so

r =.0375 Multiply by 100 to get the percent of 3.75%
