Answer:
$93.00
Explanation:
To find out how much the office manager will spend on office supplies (before sales tax), we must add the costs of the pens, paper clips, paper, and legal pads.
⟹ pens + paper clips + paper + legal pads
⟹ $20 + $15 + $30 + $28
⟹ $93
Therefore, the subtotal will be $93 before sales tax.
