The price of a pair of jeans is $25. If there is a 15% discount, what is the sale price of the jeans?
dusya [7]

Answer:

$29.41

Step-by-step explanation:

You know the discount price is 25 and the original is unknown so call it x. The sale is 15% off and that means that the jeans are 85% of what they used to be since 100-15 is 85. Then you plug it into a formula of 25/x = 85/100 then you cross multiply to get 2500=85x and when you solve for x and round you get $29.41

Evaluate the expression. 5 x (-6 / -1 + -10)
kotykmax [81]

Answer:

-20

Step-by-step explanation:

5 * (-6 / -1+ -10)

According to PEMDAS, we need to do the math in the parentheses first.

-6 / -1 + -10

Applying PEMDAS to the inside of the parentheses, then we have to divide -6 by -1, where we would get 6.

6 + -10

Adding a negative is the same as subtracting, so adding negative 10 is the same as subtracting 10.

6 - 10

Subtracting, we get 6 - 10 = -4 and we're left with:

5 * (-4)

Multiplying, <u>our final answer is -20.</u>

Hope this helps!
