Question

Phil had 93 dollars, and his sister owed 10 dollars to her friend. How much should Phil give to his sister for each of them to have the same amount after she paid her debt?

Answer 1

they should both be $41.5 and Phil should give $51.5 to her sister.

Explanation:

first, you find the mid point of 93 and -10

so,

(93+(-10))÷2=41.5

then 93-41.5

which equaled to 51.5

Answer 2

Phil should have $41.5 and Phil should give $51.5 to her sister.

Explanation:

Given that,

amount of money Phil have = $93

amount of money Phil's sister owed to her friend = 10

$10 of the $93 is going to his sister's friend; that leaves $83 for Phil and his sister.

If they are to finish with the same amount, then each should have half of the Phil's money after she paid $10

So,

83/2

= 41.5 each but since Phil's sister have to give 10 rupees in debt so

41.5+10

= 51.5

So Phil should have $41.5 and Phil should give $51.5 to her sister.
