Question

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 she have left for gift C? Solve

Answer 1

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)`
