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 $320 per week at the mall. What is the hourly wage at the mall?
let the hourly wage at mall=$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
