1/2x + 5 = 35

You use 1/2 because she sold half of her books . Then +5 because she gained 5 back and 35 because your end total should be 35.

Hope this helps ! :)

Mathematics

Original Interest: I = Prt
I = (3000)(0.02)(8)
I = (60)(8)
I = 480

Simple Interest: A = P(1 + rt)
A = 3000(1 + (0.02)(8))
A = 3000(1 + 0.16)
A = 3000(1.16)
A = 3480

Compound Interest: $C = P((1 + r)^{n} - 1)$
$C = 3000(1 - 0.02)^{96} - 1)$
$C = 3000((0.98)^{96} - 1)$
C = 3000(014 - 1)

Payment Amount: $A = P\frac{r(1 + r)^{n}}{(1 + r)^{n} - 1}$
$A = 3000(\frac{0.02(1 + 0.02)^{96}}{(1 + 0.02)^{96} - 1})$
$A = 3000(\frac{0.02(1.02)^{96}}{(1.02)^{96} - 1})$
$A = 3000(\frac{0.02(6.7)}{6.7 - 1})$
$A = 3000(\frac{0.134}{5.7})$
A = 3000(0.024)
