The earnings of Tom is $510.
A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.
For the given situation,
Let the earnings of Jan be x and
Let the earnings of Tom be y.
Jan earned $150 less than twice Tom's earnings,
⇒ ------ (1)
Together Jan and Tom earned $1380,
⇒ ------- (2)
Now substitute equation 1 in 2,
⇒
⇒
⇒
⇒
⇒
Hence we can conclude that the earnings of Tom is $510.
