Charles buys 60 packs of pens. There are 12 pens in each pack.
Each pack costs £2.80.
Charles sells each pen for 40p but he only manages to sell
2/3
of the pens.
How much profit did he make

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)

i those same problems in math and dont know how to do them

whats the rest of it?
