NEED HELP ASAP
Stanley has a rich uncle who wishes to give Stanley $10000
on his 25th birthday. How much will the uncle have to
invest now, if Stanley has just turned 17 and the money
will go into a savings account that pays 7.5% compounded
semi-annually?

Well, we know that Stanley has to wait 8 years. Since we are given a rate in half-years, we convert that 8 to 16 half - years.

Then, we write an equation where x is the original amount.

x * 1.075^16 = 10000

Then, we solve.

That gives us about $3,143.87.

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
