Question

A man has 350 watches. He sells ‘w’ watches everyday. Write an algebraic
expression to show the number of watches he would be left with after ‘t’ weeks.

Answer 1

Answer:

350 - 7tw or 7(50 - tw)

Step-by-step explanation:

Total no. of watches = 350

No. of watches sold in 1 day = w

No. of watches sold in 1 week = 7w

No. of watches sold in 't' weeks = 7tw

So, no. of watches left after 't' weeks = 350 - 7tw
