Afactory makes toy cars. each toy car has 4 wheels. a total of 34 toy cars were made on monday. if twice as many cars are made on tuesday, how many wheels will be needed on monday and tuesday?

For a total your going to need 408 wheels for monday and tuesday

So to start you must find out how many cars they made on Tuesday. 34 x 2 = 68. Then add Monday and Tuesday's numbers to get the total number of cars made. 68 + 34 = 102. Now you must multiply the number of wheels each car needs by the total amount of cars. 102 x 4 = 408. The total number of wheels needed for Monday and Tuesday is 408.
