Answer:
If the item is on sale for 60% off the regular price, then the sale price is:
Sale price = Regular price - Discount
where the discount is 60% of the regular price:
Discount = 60% × Regular price
Substituting the value of regular price as $70:
Discount = 60% × $70 = 0.60 × $70 = $42
So, the sale price is:
Sale price = $70 - $42 = $28
Therefore, the sale price of the item is $28.
