To calculate the salesman's earnings for that month, we need to consider his salary and commission on sales.

The total amount from selling 150 cellphones at 15000sh each is 150 * 15000sh = 2,250,000sh.

Since this amount is below 1,000,000sh, the salesman doesn't receive any commission slab. Therefore, his commission for that month is 0%.

His salary remains the same at 20,000sh.

Therefore, his total earnings for that month are 20,000sh (salary) + 0sh (commission) = 20,000sh.
