You buy a pair of jeans at a department store. Jeans 39.99 Discount -10.00 Subtotal 29.99 Sales tax 1.95 Total 31.94 a. What is the percent of discount to the nearest percent? The percent of discount is ___%. b. What is the percent of sales tax to the nearest tenth of a percent? The percent of sales tax is ___% c. The price of the jeans includes a 60% markup. After the discount, what is the percent of markup to the nearest percent? The percent of markup is ___%

The discount offered on the jeans is 25 percent. The sales tax charged on the jeans is 6.5 percent. Markup on the jeans after allowing discount is 60 percent.

a. To find the percent of discount, we need to calculate the actual discount and divide it by the original price, then multiply by 100. From the given information, the original price of the jeans is $39.99 and the discount is $10.00. Therefore, the actual discount is $10.00 and the original price is $39.99. The percent of discount to the nearest percent is:

Percent of discount = (actual discount / original price) x 100

Percent of discount = (10.00 / 39.99) x 100

Percent of discount = 25%

Therefore, the percent of discount to the nearest percent is 25%.

b. To find the percent of sales tax, we need to divide the sales tax by the subtotal, then multiply by 100. From the given information, the subtotal is $29.99 and the sales tax is $1.95. Therefore, the percent of sales tax to the nearest tenth of a percent is:

Percent of sales tax = (sales tax / subtotal) x 100

Percent of sales tax = (1.95 / 29.99) x 100

Percent of sales tax = 6.5%

Therefore, the percent of sales tax to the nearest tenth of a percent is 6.5%.

c. The price of the jeans includes a 60% markup, which means that the selling price is 160% of the cost price. Let x be the cost price of the jeans. Then, the selling price of the jeans is 1.6x. After the discount of $10.00, the selling price becomes 1.6x - 10.00. The percent of markup after the discount to the nearest percent is:

Percent of markup = ((selling price - cost price) / cost price) x 100

Percent of markup = (((1.6x - 10.00) - x) / x) x 100

Percent of markup = (0.6x - 10.00) / x x 100

Percent of markup = 60 - (1000 / x)

Percent of markup = 60%.

So, the percent of markup after the discount is approximately 60%.

The table shows how an elevator 500 feet above the ground is descending at a steady rate. Which equation represents the height, h(t), of the elevator in feet, as a function of t, the number of seconds during which it has been descending? h(t) = 5t + 500 h(t) = 5t – 500 h(t) = –5t + 500 h(t) = –5t – 500
