Convert the integer to a fraction with a denominator of 8 by multiplying it by 8/8.

$2\times\dfrac{8}{8}=\dfrac{2\times 8}{8}=\dfrac{16}{8}$

Now, add the fractional part of the mixed number.

$2\frac{5}{8}=\dfrac{16}{8}+\dfrac{5}{8}=\dfrac{16+5}{8}\\\\=\dfrac{21}{8}$

D. $ 760

Step-by-step explanation:

Let, she pays P dollars in additional interest each year,

Since, time, t = 5 years,

Annual rate of interest, r = 3 %,

Thus, the simple interest she earned,

$S.I. = \frac{P\times r\times t}{100}$

$=\frac{P\times 3\times 5}{100}$

$=\frac{15P}{100}$

According to the question,

$\frac{15P}{100}=114$

$\implies P =\frac{11400}{15}=\$ 760$

Hence, she pays $ 760 in additional interest each year.
