What does "meet the schedule" mean from statement 2? If it means "complete the order", then I think the answer is C. If it means, get back to the rate in which is needed to complete the order, I think it's E... I think it means "complete the order", so I'd say the answer is C, which makes me hesitant because it seems to be too obvious, but here's my logic: we know from the stem that it's going to take an average rate of 1000 tools/day and we're asked for the total number or days, n, to complete the order. Because we know that they're not going to give us n directly, we need to find the work (w) for the equation: rate x time= work. Looking at the statments:
1. ok, we're given the rate time and work for the first five days: 600 tools/day for 5 days. So, 3000 tools total. Can't do anything with that.
2. We know that to "meet the schedule" which I take to mean "complete the order", the manufacturer had to crank it up to 1,500 tools/day for the last 4 days. So, the last four days, there were 6000 tools produced. I initially thought this info would be sufficient to answer the question. However, there are a number of combinations of different rates over different periods of time that we average with the rate and work for what's given in statement 2 to get to 1000 tools/day. Because of that, there's more than one answer and 2 is insufficient.
1&2 together: If we know what it took to complete the order from statement 2, then we can plug statement 1 in to the average RTW matrix to get the total number of days, n, which is 9.
I'd love to hear other's thoughts on this one. I'm definitely overthinking it.
