Supervisor’s memo: At the present rate of manufacture we will not have the 1,200 circuit boards assembled in time to ship them to the customer. We currently have 10 workers, working 8 hours a day, assembling the boards, and to date they’ve assembled 400. In order to finish the customer’s order in time, I’ll need to have each of the workers work an additional 2 hours for each of the 10 work days between now and the deadline.
One can determine the hourly rate at which each worker assembled circuit boards up to the date of the supervisor’s memo by dividing ___1___ circuit boards by the product of ___2___ worker-hours and the number of days since the workers began assembling the circuit boards.
Select "Circuit boards" for the option that fills the blank labeled 1 in the given statement, and select "Worker-hours" for the option that fills the blank labeled 2 in the given statement to create the most accurate statement on the basis of the information provided. Make only two selections, one in each column.Circuit boards----Worker-hours
A) 80-----------------------80
B) 400---------------------400
C) 500---------------------500
D) 800---------------------800
E) 1,000-------------------1000
F) 1,200-------------------1200
400 Circuits Boards and 80 Worker Hours.
Till Memo Data:
We currently have 10 workers, working 8 hours a day, assembling the boards, and to date they’ve assembled 400.
So hourly rate of work done (how much work is done each hour) till now = Work/Time
Work done = 400 boards
Time taken in hrs = 10 * 8 * N (N is the number of days for which they worked) = 80N hrs
10 workers worked for 8 hrs every day so every day 80 worker hrs were being put in and this was done for N days giving us 80N total worker hrs put in.
Hourly rate of work done = 400/80N
To finish:
In order to finish the customer’s order in time, I’ll need to have each of the workers work an additional 2 hours for each of the 10 work days between now and the deadline.
One can determine the hourly rate at which each worker assembled circuit boards up to the date of the supervisor’s memo by dividing _______________ circuit boards by the product of ______________ worker-hours and the number of days since the workers began assembling the circuit boards.
How did we get hourly rate till memo date? Work done till memo date/Total worker hrs taken till memo date = 400/80N
So we divide 400 boards by product of 80 worker hrs and N, the number of days.
Hence the two blanks will have 400 and 80 respectively.
