Hello everyone and welcome.

This question is asking us about the amount of time it takes to build first five units given that the first unit took 1 ,000 hours to build and there's a 85 % productivity.
00:14
So this is nothing that a little bit of brute force really can't solve.
00:19
So we're going to have to use a calculator quite a bit here.
00:22
So we've got the first unit.
00:25
We've got the second unit, third, fourth, and fifth.
00:36
We just have to calculate what each of these values are going to be for each unit.
00:42
So we start with 1 ,000 hours and it's decreasing by 15 % each time.
00:49
So 85 % of 1 ,000 is 850 hours.
00:54
So we've got 850.
00:57
Next we've got 85 % of 850, which is 772 .91 hours.

And i already did these ahead of time in the calculator just for the sake of...
