Ann and Bill share an amount of money in the ratio 7 : n Ann gets 28% of the money

Work out the value of n.
Your final line should say, n = ...

the equation of the line that passes through the points and has o form

if line passes through the points (-1, -3) and (2, 1), then

the equation in the standard form is

the formula for converting absorbance to transmittance goes as:

a = log (1/t)  a = 2 - log(%t)  10^a = 1/t  t = 10^-a  %t = 100(10^-a)

so at the given value of a,   a = 1.5

%t = 100(10^-1.5)

%t = 3.16%

(a)   the cost of the fruit in $2 per lb = slope of the line

a cost of $10 ( the height of the vertical axis) and a weight of the strawberries ( the corresponding point on x axis)

so the lope   is   10/5 = 2   that is $2 per lb of strawberries

cost = 2w   where   w = weight of strawberries in pounds

(b) in the same   way cost of each lb of   blueberries = 10/7 =   $ 1.43

cost =   10w/7     where w = weight of blueberries in lbs.

c)     blueberries are cheaper ( $1.43 / lb against   %1 per lb for strawberries)

i tried my best if i'm right if i'm wrong i am so sorry.but if i am right plzzz mark brainliest: )
