Answer:
Explanation:
If she needs 17350 and she already has 14000, she only needs 3350 more to buy the car. We can use the simple interest formula to find out how long, in years, she has to leave her 14000 in the bank to make up the 3350 she needs. The formula for simple interest is I = prt, where I is the interest earned, p is the initial investment, r is the interest rate in decimal form, and t is the time in years. Our initial investment is the 14000; our interest rate is .08, we are solving for t, and the interest she needs to earn is the difference between what she already has and what she needs which is 3350.
3350 = 14000 * .08 * t and
3350 = 1120t so
t = 2.99 years or 3 years
