When comparing two jobs, Chris noticed that the hours every week were the same at each, but the job at the hospital paid $3.00 per hour more than the job at the mall. She can earn $440 per week at the hospital and $320 per week at the mall. What is the hourly wage at the mall?

Verified Answer :

let the hourly wage at mall=$x
number of hours=320/x
then hourly wage at hospital=$
x+3
number of hours=440/(x+3)
\(now \frac{320}{x} = \frac{440}{x+3} cross multiply 440x=320(x+3) 440x=320x+960\)\(440x-320x=960 120x=960 x= \frac{960}{120} =8\)
so hourly wage at mall=$8

Answer:

$8

Step-by-step explanation:

Let the hourly wage of mall be x

Since we are given that  the job at the hospital paid $3.00 per hour more than the job at the mall.

So, hourly wage at hospital = x+3

Now She can earn $440 per week at the hospital

So, no. of hours she worked in hospital = @@MATH_TOKEN_0@@

Now she can earn $320 per week at mall

No. of hours worked at mall = \(\frac{320}{x}\)

Since we are given that the hours every week were the same at each

⇒ \(\frac{320}{x}=\frac{440}{x+3}\)

⇒ \(320(x+3)=440x\)

⇒ \(320x+960=440x\)

⇒ \(960=440x-320x\)

⇒ \(960=120x\)

⇒ \(\frac{960}{120}=x\)

⇒ \(8=x\)

Hence the hourly wage at mall is $8
