Question

Art is a skilled worker in a precision optical instrument factory. He is paid $1 per hour plus an additional $5 per hour for each microscope he assembles in that hour. If Art assembles a microscope every 20 minutes over the course of an 8 hour work day, what is Art’s resulting hourly wage, and how much does he make in a four week month with 5 work day months? Both parts of an answer must be correct.

(a) $23/hour, $2,100/month (b) $16/hour, $2,400/month (c) $17/hour, 384 microscopes

(d) $20/hour, $1,920/month (e) $16/hour, $2,560/month (f) none of the above

Answer 1

9514 1404 393

Answer:

(e) $16/hour, $2560/month

Explanation:

At one assembly per 20 minutes, Art assembles 3 microscopes per hour. That means each hour he gets paid $1 + 3×$5 = $16.

There are 8×5 = 40 hours in a work week, and 4×40 = 160 hours in a month. Art's pay for the month will be ...

($16/h)(160 h) = $2560

Art's pay is $16 per hour, and $2560 per month.
