Alana earnerd money doing chores. Her grandmother agreed to add $4.00 to the amount Alana earned and then give her half of that

vitfil [10]

Answer:

Hence amount of Alana's donation is $4.5.

Step-by-step explanation:

Amount of Alana's donation = x

Her grandmother agreed to add $4.00 to the amount Alana earned.

So new amount of money = (x+4)

She gives only half of the sum which is (x+4)/2.

She gave her $4.25 so both values must be equal.

$\frac{\left(x+4\right)}{2}=4.25$

$x+4=4.25*2$

$x+4=8.5$

$x=8.5-4$

$x=4.5$

Hence amount of Alana's donation is $4.5.
