Answer:
He needs an extra $13.
Step-by-step explanation:
In total, he needs $26 to get all three toys.
His allowance plus money he received from his uncle is $13.
So you take the total amount that he needs subtracted by the amount he already has.
As an equation, it would look like $26 - $13 = $13
Hope that helped!
He needs $13 more dollars because 5+12+9=26 and 8+5=13 then you do 26-13=13
