Answer:
Option A = 75 is the best option
Step-by-step explanation:
It took Ashlie 2.5 hours (11:30 am - 2pm) to assemble the marketing packets
Rate = Number of jobs done/Time taken = 90 packages/hr
Number of jobs done = Rate * Time taken = 90 * 2.5 = 225 packages.
Dwayne has assembled the same number of packages = 225 (as reported in the question),
It took Ashlie 2.5 hours (11 am - 2pm)
Then, his work rate is calculated as: Number of jobs done/Time taken = 225 packages/3 hours = 75
Thus, option A = 75 is the best option
The rate per hour for Dwayne to assemble the packets is 75 packets.
Ashlie starts assembling marketing packets at 11:30 a.m. and assembles at a rate of 90 packages per hour.
Dwayne starts assembling marketing packets at 11 a.m.
Now, at 2 PM Ashlie worked 2.5 hours and Dwayne worked 3 hours.
According to the question, Ashlie and Dwayne assemble the same number of packages at 2 PM.
Therefore,
The number of packages assembled by the Ashlie till 2 PM can be calculated as:
[tex]\begin{aligned}\rm{Assembled\;by\;Ashlie}&=\rm{Rate \times Time \;taken }\\&=2.5 \times 90\\&=225 \;\rm{Packets}\end{aligned}[/tex]
Now, the same number of packets is assembled by Dwayne.
Therefore,
[tex]\begin{aligned}\rm{Assembled\;by\;Dwayne}&=\rm{Rate \times Time \;taken }\\225&=3 \times \rm{Rate}\\&\rm{Rate}= 75\;\rm{Packets\;per\;hour}\end{aligned}[/tex]
Thus, the rate per hour for Dwayne to assemble the packets is 75 packets.
