Question

A manufacturer of computer logic boards is changing to a new model. The amount of time to setup for the new logic boards is

10.5 hours, and each new batch takes 4.25 hours to produce. Which solution is viable for the total amount of time spent to
manufacture completed batches of logic boards?

O 1.5 batches take 12.375 hours
O 4 batches take 17 hours
O 2 batches take 29.5 hours
O 5 batches take 31.75 hours

Answer 1

1.5 batches take 12.375 hour

Explanation:

The first batch takes 10.5 hours, meaning only .5 batches are left. You then take the time that each new full batch takes (4.25) and divide it by 2 as you only need half of one batch. Meaning 0.5 of a batch takes 2.125 hours. You then take the time of the two batches (10.5, and 2.125) and add them, leaving you with 12.625. Meaning 12.375 is the most viable answer.
