Answer:

The correct answer is 13!

Step-by-step explanation:

I just did this, it is not 15! because there are two kids who have to be in a certain spot no matter what else the other kids do so 15-2=13

13 kids can change positions so 13!

at a clothing store, levi's jeans are on sale for 40% off. sales tax is 7%. which expression will calculate the total cost of le
aleksandrvk [35]

Given:

Discount = 40%

Sales tax = 7%

To find:

The total cost of levi jeans with an original price of x.

Solution:

Let x be the original price of the jeans. Then the price after 40% discount is

Price=x-40\%\text{ of }x

Price=x-\dfrac{40}{100}x

Price=x-0.4x

Price=0.6x

The price after 7% of sales tax.

Price=0.6x+7\%\text{ of }0.6x

Price=0.6x+\dfrac{7}{100}\times 0.6x

Price=0.6x+0.042x

Price=0.642x

Therefore, the total cost  of the levi jeans with an original price of x is represented by the expression 0.642x.
