Question

LAST PROBLEM FOR TODAY

Answer 1

Joselyn is a manager at a sign-painting company. She has two painters, Allen and Brianne. Allen can complete a large project in 16 hours. Brianne can complete the project in 18 hours. Joselyn wants to know how long it will take them to complete the project together.

Write an equation and solve for the time it takes Allen and Brianne to complete the project together. Explain each step.

Answer 2

Sorry I am lagging .

Allen can complete 1/16 of the work in an hour , Brainne can complete 1/18 of the work in an hour

(1/16 + /18 )t = 1
t = 8.5 hour

Answer 3

wow thank you! can you give me the basic steps in the process? just tryin to get full credit

Answer 4

Trying to type bad damn mouse and network

Answer 5

no worries i have time

Answer 6

if allen can finish the whole job in 16 hours , then he can finish 1/16 of the job in 1 hour

if brainne can finish the whole in 18 hour then he can finish 1/18 of the job in 1 hour

Use this formula

amount of work done per hour * time = number of jobs

wt = j

in your case

t = 16 , j = 1 ( for allen)
w = 1/16

for the other:

t = 18, j = 1

18w = 1

w = 1/18

Use the same modified version:

you want both of them to work ( same time) and do the same job

w1 t + w2 t = j (w1 for allen, w2 for brainne)

(1/16 + 1/18)t = 1
t = 8.5

Answer 7

Thank you I understand now.

Answer 8

Any time

Answer 9

i explained that previously

Answer 10

Yeah I actually just saw your response. I used it.
