John earns $50 less than three times as much as sam each week. together sam and john earn $1200 a week. how much does sam earn question

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
