Answer:
$3.125
Step-by-step explanation:
Selling Price = $2.50
Unit Cost = $1.00
Gross margin = (Unit cost/Selling price)*100
= (1/2.5)*100
Gross margin = 40%
Unit cost increased by 0.25.
New unit cost = $1.00 1+ $0.25 = $1.25
Selling price =( Unit cost/Gross margin)*100
Selling price =[ (1.25)/40]*100
= 125/40
Selling price = $3.125
Increases the unit selling price to $3.125
Hope this will helpful.
