The answer is 10.

12➗3=4 meaning she makes 4 trains per hour. Now you do 4•2.5 which is 10

Answer:

22

Step-by-step explanation:

If in 3 hours she made 12

if we divide 12 and 3

she is making 4 every hour

she already has 12 so if you add 8 to that it will be 20

then 30 minutes she will make half the toys she makes in an hour will be 2

add 20 and 2 you get 22 and thats your answer
