Yes, you need to make the denominators the same. 2/3 becomes 8/12. So now you add 7/12 and 8/12, getting 15/12. But you're not done you need to simplify 15/12. The answer is 1 1/4.

3. How much interest does $5300 earn at a rate of 2.8% interest compounded quarterly after 6

azamat

Answer:

The interest is $I=\$74.46$

Step-by-step explanation:

we know that

The compound interest formula is equal to

$A=P(1+\frac{r}{n})^{nt}$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

$t=6/12=0.5\ years\\ P=\$5,300\\ r=0.028\\n=4$

substitute in the formula above

$A=5,300(1+\frac{0.028{4})^{4*0.5}$

$A=5,300(1.007)^{2}$

$A=\$5,374.46$

<em>Find the interest</em>

$I=A-P$

substitute

$I=\$5,374.46-\$5,300=\$74.46$
