Answer:
Discount is 13.75 discounted price is 11.25
Step-by-step explanation:
Answer: $11.25
Given that item is $25 before sale, susan bought for 55% off the regular price.
55% off $25 implies subtract 55% from $25
=55/100 × 25 = $13.75
Susan therefore bought the item at $25 - $13.75 = $11.25.

f'(x)=6x+8

x = 20√2 and y = 20√3.
or x = 28.28 and y = 34.64 to the nearest hundredths.
Take the 2 'inside' triangles. They are similar.
So we have x / (60-40) = 40 / x
x/ 20 = 40 /x
x^2 = 800
x = √800
x = 20√2
y = √(800 + 20^2)
= √(1200)
= 20√3.
f(16)= -8
f(16)= 1/3(4-16)2
