Jenny examined the 14 machine parts made in an hour at a factory. She found that 3 of the parts were broken. If this pattern continues for the next four hours, Jenny wants to find how many parts the factory will make in four hours that are
NOT broken.
Drag and drop the responses into the boxes below to create the expression that Jenny needs to represent this situation.

44 machine parts won't be broken.

Step-by-step explanation:

14 per hour

3 out of those 14 was broken

14 - 3 = 11 that will turn out, not broken

11 per hour

if we're going to work out 4 hours we need to multiply it by 4

11 × 4 =44

1 × 4 = 4

44 per hour that will not turn out broken because we disincluded the broken parts that will be there.

answer is 144
