Question

The number of sofas a factory produces varies directly with the number of hours the machinery is operational. Suppose the factory can produce 455 sofas in 48 hours. What is an equation that relates the number of sofas produced, n, with the amount of time, t, in hours? What is the graph of your equation?
A. n = 9.48t


B. n = 0.11t



C. t = 4.74n



D. t = 9.48n

Answer 1

i know it is not (D)

Answer 2

455 sofas in 48 hours
1 sofa in 48/455 hours= 0.105 hours

Answer 3

or in 48 hours 455 sofa
in 1 hour number of sofa= 455/48=9.47 sofas

Answer 4

therefore t=9.48 n

Answer 5

so it is (A)

Answer 6

it's D

Answer 7

i got that wrong when i put (D) =(

Answer 8

They probably used t for time and n for number of sofas.

Answer 9

i think (B)

Answer 10

then i guess ..may be there answer is wrong ...because whole explanation is in front of you :)

Answer 11

no it can't be B or C

Answer 12

then i will go with (A)

Answer 13

n=kt
455=k(48)
k=455/48
n=(455/48)t
n=9.48t

Answer 14

thanks =)

Answer 15

You're welcome.
