i.

ii.

Step-by-step explanation:

Given

Commission = 0.5% of Monthly Sales

Calculating his total income is total sales is  Rs 720,000

Substitute (0.5% of Monthly Sales) for Commission

Substitute Rs 720,000 for Monthly Sales and Rs 12,500 for Salary

Convert % to decimal

Calculating his total sales if total income = Rs 20,000

Recall that;

Substitute Rs 20,000 for Total Income; Rs 12,500 for Salary and (0.5% of Monthly Sales) for Commission

Subtract Rs 12,500 from both sides

Divide both sides by 0.5%

Convert % to decimal
