Is this correct? Please tell me if its right or not its very overdue!! Also if it's wrong please tell me the answer/what to do! question:

When Jack turned 21, he decided to start investing $200 a month every year for nine years. At age 30, he decided to stop investing altogether.

Blake started a little later, investing $200 a month every month starting at age 30, all the way until the ripe old age of 67.

Assuming that they were both amazing at investing and made 11% interest per year, how much money will they both have at age 67?

my

200 x 12 = 2400 per year

Jack:

2400* (1.11/1) ^ (1*46) = 291788.56346755

Blake:

2400 * (1.11 * 1) ^ (1 * 37) = 114067.3775

i think its right   sorry if am wrong

Step-by-step explanation:

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )
