After ricardo received his allowance for the week he went to the mall with some friends he spent half of his allowance on anew paperback book the he brought himself a snack $1.25 when he arrived home he had $5.00 left how muchwas his allowance

$12.50

Step-by-step explanation:

Let Ricardo received the allowance = x dollars.

He spent half of her allowance on a new paper back book

so amount left with him = x -

                                      =

then he bought a snack with the amount = $1.25

amount left = ( - 1.25)

When he reached home amount with him = $5.00

Therefore, -1.25 = 5

                = (5 + 1.25)

                = 6.25

                x = 2 × 6.25

                x = $12.50

Ricardo received allowances = $12.50
