Answers
Answer:
In 1h Donna completes X report
In 1h Denise completes Y report
let Danny works for K hour
so according to the question Denise works for (K+L) hr
so In K hour Donna completes KX report
In (K+L) hour Denise completes (K+L)X report
so total report=KX+(K+L)X=2KX+LX
Answer: Kx + Lx + Ly where Denise works for K hours.
Step-by-step explanation:
Donna completes reports in one hour = x
Denise completes reports in one hour = y
Let us assume Denise works of K hours.
According to question Donna works L hours more than Denise.
So Donna will work for (K +L) hours.
∴ Total reports = (Donna's completed reports in 1 hour *time taken by Donna) +(Denise completed reports in 1 hour *time taken by Denise)
= (K + L)x + Ly
= Kx + Lx + Ly
