a bicycle shop is offering a 15% discount on a bike that has an original price of 275. there is an additional 5% discount off the sale price. what is the final price of the bike, including both discounts?

Step-by-step explanation:

• the original price= 275,

275 → 100 %

i) find the price with the 15 % discount

100% - 15% = 85 %

if, 275 → 100 %

100 % → 275

1% → 275 / 100

85 % → (275/100) * 85

= 233. 75

ii) find the add. 5% of the :

sale price = 233. 75

add. discount = 5%

= 5/ 100 * 233.75

= 11.6875

iii) subract the 5% discount from the sale price.

final price = 233. 75 - 11.6875

= 222. 0625

hope this helps you!

-s.

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
