Tavius wants to invest $2,500. Which option will earn him the best value?
Step2247 [10]

Tavius would earn his best value if he invests in a  three-year certificate of deposit with a nominal interest rate of 4 percent.

Tavius would invest in the option that yields the highest interest. This is the best value. In order to determine which option is the best, the interest rate of each option has to be determined.

<em><u>Interest rate of the first option</u></em>

Interest earned = amount invested x time x interest rate

$2500 x 0.03 x 2 = $150

<em><u /></em>

<em><u>Interest rate of the second option</u></em>

Interest earned = amount invested x time x interest rate

$2500 x 0.03 x 1 = $75

<em><u /></em>

<em><u>Interest rate of the third option</u></em>

Interest earned = amount invested x time x interest rate

$2500 x 0.04 x 3 = $300

<em><u /></em>

<em><u>Interest rate of the fourth option</u></em>

FV = P x (1 + r) n

$2500 x (1.03) = $75

A car is traveling at a steady speed. It travels 1 3/4 miles in 2 1/3 minutes. How far will it travel in 45 minutes? In 1 hour?
mina [271]

Answer:

33.75 miles in 45 minutes,

45 miles in an hour

Step-by-step explanation:

45 minutes: 2 1/3= 7/3 ---> 7/3*3=7,

                    1 3/4= 7/4 ---> 7/4*3=5.25

car travels 5.25 miles for every 7 minutes,

45/7*5.25= 33.75 miles

1 hour (60 minutes):

using that the car travels 5.25 miles for every 7 minutes,

60/7*5.25= 45 miles

Hope that makes sense!
