The original price of a jacket for sale at a department store is $80. the store is having a 20%-off sale, and you have a coupon that gives you an additional discount of 10% off the lowest sale price. how would you calculate the final selling price of the jacket?

Start with the original price, $80.

If you take 20% off, then you will be paying 80% of the original price. Calculate 80% of $80.

80% of $80 = 80% * $80 = 0.8 * $80 = $64

After applying the 20% discount, the new price is $64.

Now you apply the 10% coupon.

Since you are taking 10% off the discounted price, you will be paying 90% of the discounted price.

90% of $64 = 0.9 * $64 = $57.6

The final discounted price is $57.60

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

what is the answer?
