Hannah had 30 dollars to spend on 3 gifts. She spent 8 7 10 dollars on gift A and 4 2 5 dollars on gift B. How much money did sh

Dimas [21]

Answer: $\$16\dfrac{9}{10}$

Step-by-step explanation:

Given

Hannah had 30 dollars

Money spent on gift A

$8\ \dfrac{7}{10}=\dfrac{8\times 10+7}{10}=\dfrac{87}{10}$

money spent on gift B

$4\ \dfrac{2}{5}=\dfrac{22}{5}$

Money spent on gift C

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