Answer:
16 hours
Step-by-step explanation:
let t be time, n the number of computers and w the number of workers, then
t =
← k is the constant of variation
To find k use the condition n = 30, w = 6 and t = 10 , then
10 =
( multiply both sides by 6 )
60 = 30k ( divide both sides by 30 )
2 = k
t =
← equation of variation
When w = 5 and n = 40 , then
t =
=
= 16 hours
Ummm not to freak you out but what’s that in the background?
"Increased by" means to multiply.
First, change the percentage to a number.
% ⇒ # : %/100
120(%) (120 ÷ 100) = 1.2
Now, you multiply.
5x × 1.2 = 6x
So, your answer is 6x.
