Bhu had $48, but received $100 as a birthday gift and used the money to pay off her debt. She spent half of the money on a gift for herself. Which expression BEST represents the number of dollars Bhu has left?

a.(-48+100)÷2
b.(48+100)÷2
c.-48+100÷2
d.2(48+-100)

( 48 + 100 ) - 1 / 2 ( 48 + 100 ) =

( 48 + 100 ) / 2

To find the number of dollars Bhu has left, we need to calculate the amount of money she started with, plus the birthday gift, minus the amount she spent on a gift for herself. Here is the breakdown of the problem:

Bhu started with $48.
She received $100 as a birthday gift.
She spent half of the money on a gift for herself.

To calculate the number of dollars Bhu has left, we can use the following expression:

(48 + 100) - (1/2) * (48 + 100)

Simplifying the expression further:

148 - 0.5 * 148

Now we can solve the expression:

148 - 74

Therefore, Bhu has $74 left.

Out of the answer options provided, the expression that represents the number of dollars Bhu has left is:

b. (48 + 100) ÷ 2
