Answer:
$\$16(9)/(10)$

Explanation:

Given

Hannah had 30 dollars

Money spent on gift A

$8\ (7)/(10)=(8* 10+7)/(10)=(87)/(10)$

money spent on gift B

$4\ (2)/(5)=(22)/(5)$

Money spent on gift C

$\Rightarrow \text{Total-Money spent on (A+B)}\\\\\Rightarrow 30-(87)/(10)-(22)/(5)=30-(87)/(10)-(44)/(10)\\\\\Rightarrow (300-87-44)/(10)=(169)/(10)\\\\\Rightarrow \$16\ (9)/(10)$
