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 cell phone battery uses 1/3 of its charge in 3/8 of a day. How much charge will it use in one day?​
brilliants [131]

\bf \begin{array}{ccll}charge&day\\\cline{1-2}\frac{1}{3}&\frac{3}{8}\\\\x&1\end{array}\implies \cfrac{~~\frac{1}{3}~~}{x}=\cfrac{~~\frac{3}{8}~~}{1}\implies \cfrac{~~\frac{1}{3}~~}{\frac{x}{1}}=\cfrac{3}{8}\implies \cfrac{1}{3}\cdot \cfrac{1}{x}=\cfrac{3}{8}\\\\\\\cfrac{1}{3x}=\cfrac{3}{8}\implies 8=9x\implies \cfrac{8}{9}=x

A store manager is marking down chess boards from $25 to $14. What percentage is the discount?
Alborosie
Remember: when calculating percent it will always be over 100. With the given numbers 14 is your part out of the total (25). It should be written as part/whole.

As previously said, the percent is always over 100. (x/100)

In this problem you are given the part (14) and the whole (25). So it would be 14/25. The percent in this problem would be x/100. Now to find percent with the given part/whole, you would multiply 14 with 100. Then simply divide by 25.
