3 7/8

So we can use this $a \frac{b}{c} = \frac{(a \times c) + b}{c}$

So we get

$3 \frac{7}{8} = \frac{(3 \times 8) + 7}{8}$

= $\frac{24+7}{8} = \frac{31}{8}$

Answer: 1902.36

Step-by-step explanation:

When interest is compounded monthly , the formula to find the accumulated amount is

$A=P(1+\dfrac{r}{12})^{12t}$ , where P = principal value , r = rate of interest , t = time.

As per given,

r= 24% = 0.24

P= $1500

t= 1 year

Put all value in formula , we get

$A= 1500(1+\dfrac{0.24}{12})^{12\times 1}\\\\=1500(1+0.02)^{12}\\\\=1500(1.02)^{12}\\\\=1500(1.26824179456)\approx1902.36$

Hence, he need to pay $1902.36.
