Zorluk: ZorPercentage Change, Markups, and Discounts

An industrial supply company purchases a heavy-duty welding machine directly from the manufacturer for $2,400.00\$2,400.00. The company applies a 40%40\% markup to establish their standard retail price. During a promotional event, a customer purchases the machine at a 15%15\% discount off the retail price. If an additional 6%6\% sales tax is applied to the discounted price, what is the total amount the customer pays in dollars?

Cevap: 3027.36 $

Cevap

3027.36
To find the final amount, each percentage change must be applied sequentially to the most recent price. First, the 40%40\% markup increases the $2,400.00\$2,400.00 base price to $3,360.00\$3,360.00. Next, the 15%15\% discount reduces this retail price to $2,856.00\$2,856.00. Finally, applying the 6%6\% sales tax to the discounted price yields a final total of $3,027.36\$3,027.36.

Adım Adım Çözüm

1
Calculate the markup amount and the standard retail price.
$2,400.00×1.40=$3,360.00\$2,400.00 \times 1.40 = \$3,360.00
The 40%40\% markup is based on the initial wholesale cost.
2
Calculate the sale price after the discount.
$3,360.00×(1−0.15)=$3,360.00×0.85=$2,856.00\$3,360.00 \times (1 - 0.15) = \$3,360.00 \times 0.85 = \$2,856.00
The 15%15\% discount is taken off the standard retail price, not the original cost.
3
Calculate the final price including sales tax.
$2,856.00×1.06=$3,027.36\$2,856.00 \times 1.06 = \$3,027.36
Sales tax is calculated on the discounted sale price to find the total amount paid.
