Question

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

Answer 1

The earning of Sam is $312.5

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 =
`(1250)/(4)` = $312.5

And ( 3 x - $50 ) = 3 × $312.5 - $50

So, = $ 887.5

Hence The earning of Sam is $312.5 Answer
