Hector's parents started saving money for his college education when Hector was six. If they save $400 per month at a credit union account, paying 2.5% interest compounded daily, how much will Hector have for college expenses 12 years later?

Answers

Answer:

$539.94

Step-by-step explanation:

The formula for calculating future value:

FV = P (1 + r/m)^mn

FV = Future value  

P = Present value = $400

R = interest rate = 2.5/ 365

N = number of years = 12 x 365

$400 x ( 1 + 0.025/365)^4380 = $539.94

Answer:

x = 11

Step-by-step explanation:

33 divided by 3 is 11, and 11 times 3 is 33.

answer:

11

step-by-step explanation:

the easiest way to explain this is just to divide

33/3

which gets you the answer of 11

but here is another way to explain this

3x = 33

since the 3 and the x are times/multiplying each other and we need to get x by its self, all we do is move the 3 to the other side ( where 33 is ) but instead of multiplying them, we have the change the sign to dividing

3x = 33

/3 ----|>

( dont forgot to rewrite the equation!! )

x = 33/3

now all we need to do is divide 33 by 3 which gives us the answer of

11
