Answer:
The Brandon did have $12.5 before going to store
Step-by-step explanation:
Let the Brandon did have money $x before going to the store.
He Spent $2.50 on pencils.
Amount left after buying a pencil = x - 2.50
Next, he spent half of the amount left in his pocket.
i.e He spent (x - 2.50)/2 on notebook and paper.
So the total amount he spent= 2.50 + (x -2.50)/2
Amount left when he got home =$ 5.00
That means, x - Total amount spent = 5
=> x - (2.50 + (x -2.50)/2 ) = 5
=> x - 2.50 -x/2 + 2.50/2 = 5
=> x/2 - 2.50/2 = 5
=> x/2 = 5 + 2.50/2
=> x/2 = 6.25
=>x = $12.5
So the Brandon did have $12.5 before going to store
