Answer 2

The expression that shows the number of watches left with him after m weeks is 200 - 7nm

Solution:

Given that,

Rishi has 200 watches

He sells n watches everyday

Therefore,

Watches sold in 1 day = n

Find number of watches left with him after "m" weeks?​

1 week = 7 days

Watches sold in 1 week = 7n

Watches sold in m weeks = $7n \times m = 7nm$

Total number of watches = 200

Number of watches left after "m" weeks = 200 - 7nm

Thus the expression that shows the number of watches left with him after m weeks is 200 - 7nm
