Step 1 :Let's denote the selling price as \(SP = \$280\)
Step 2 :Jill wants a 35% markup on the selling price, so the markup is \(0.35 \times SP = \$98\)
Step 3 :To find out the maximum cost price Jill can pay for the bedspread, we subtract the markup from the selling price, \(SP - markup = \$182\)
Step 4 :\(\boxed{\$182}\) is the most that Jill can pay for a bedspread.
