Elizabeth invested $7,800 in an account paying an interest rate of 7 1/8% compounded monthly. Mason invested $7,800 in an account paying an interest rate of 7 3/8% compounded continuously. To the nearest dollar, how much money would Elizabeth have in her account when Mason's money has doubled in value?

x=half

step-by-step explanation:

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)

the answer is 8.64

step-by-step explanation:

391.6 is the correct answer
