30% from a $28.00 shirt, what is the cost?

Answer 1

Kennedy Adams

Cost after #30%# reduction on #$28.00# would be #$19.60#

A #30%# reduction in cost implies the cost is #70%# of the original price.

#70% xx $28.00= 0.7xx$28=$19.60#

The cost of the shirt before the 30% discount is $28.00. To find the discounted price, multiply$ 28.00 by 0.30 to get $8.40. Subtract$ 8.40 from $28.00 to get the discounted price, which is$ 19.60. Therefore, the cost of the shirt after the 30% discount is $19.60.
