Answer:
The number per hour = 5400 ÷ 8 = 675 action figures
Explanation:
* Lets explain how to solve the problem
- A toy manufacturer uses 90 pints of plastic to make 600 action figures
- they use 810 pints of plastic in an 8 hour shift
- To find how many action figures are made per hour we must to find
how many action figures in an 8 hour shift and then find the number
of the action figures per hour
∵ The toy manufacture uses 90 pints of plastic to make 600 action
figures
∵ They use 810 pints
- Lets find how many action figures are made by this numbers of pints
∴ 90/600 = 810/x ⇒ x is the number of action figures
- Use the cross multiplication to find x
∴ 90 x = 810 × 600
∴ 90 x = 486000 ⇒ divide both sides by 90
∴ x = 5400
∴ They will use 810 pints to make 5400 action figures
∵ They use 810 pints in an 8 hour shift
∴ They make 5400 action figures in 8 hours
- To find the number of the action figures per hour divide the number
of them in 8 hours by 8
∴ The number per hour = 5400 ÷ 8 = 675 action figures
