The earning of Sam is $312.5
Step-by-step explanation:
Given as :
The total earning of John and Sam together = $1200 per week
Let the earning of sam each week = x
So, The earning of John is ( 3 x - $50 )
Now, According to question
John earning + Sam earning = $1200 per week
So, ( 3 x - $50 ) + x = $1200
Or, 4 x - $50 = $1200
Or, 4 x = $1200 + $50
Or, 4 x = $1250
∴ x =
= $312.5
And ( 3 x - $50 ) = 3 × $312.5 - $50
So, = $ 887.5
Hence The earning of Sam is $312.5 Answer
