An under armour shirt is listed at $65 with a discount of 5%. A similar shirt by fila sells for $85 with a discount of 8% and 3% . Calculate the additional % discount fila must give , to match the price of the under armour shirt

To match the armour shirt, fila will give additional discount of 18.6%

Step-by-step explanation:

For the armour shirt, 5% of $65 is

(5/100)*65 = $3.25

The actual selling price of armour shirt is $65 - $3.25 = $61.75

If Fila first give 8% discount, and then 3%, then we will have

(8/100)*85 = $6.80

The price will be $85 - $6.80 = $78.2

Then 3% of $78.20 is

(3/100)*78.20 = $2.35

New price is $78.20 - $2.35 = $75.85

The addition % discount will be ($75.85 - $61.75)/$75.85 × 100%

= (14.1/75.85)*100

≈ 18.6%

idk man good luck man

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
