1) A=100(1+0.05/12)^12t
2) 125=100(1+0.05/12)^12t
125/100=(1+0.05/12)^12t
Log(125/100)=12t*log(1+0.05/12)
12t=log(125÷100)÷log(1+0.05÷12)
t=[log(125÷100)÷log(1+0.05÷12)]/12

£399 is shared between Ann, Bill, Chloe and Dave.

lukranit [14]

Answer:

Ann=£38

Bill=£171

Chloe=£95

Dave=£95

Step-by-step explanation:

By the information provided we can create an equation:

$2x+9x+2*5x=399\\11x+10x=399\\21x=399\\x=19$

Now that we know x, we multiply it correspondingly.

For Ann -> 2*19=38

Bill -> 9*19= 171

Chloe and Dave have the exact same amount each (because they both have 2.5 times the amount Ann's money)

Chloe/ Dave -> 5*19=95 each.
