Assuming you are supposed to solve for the variable "t",
9 - (t ÷ 6) = 5
Subtract 9 from both sides.
9 - 9 - (t ÷ 6) = 5 - 9
Simplify.
- (t ÷ 6) = -4
Distribute -1 throughout the parenthesis.
-t ÷ -6 = -4
Multiply both sides by -6.
-t ÷ -6 × -6 = -4 × -6
Simplify.
-t = 24
Divide both sides by -1.
-t ÷ -1 = 24 ÷ -1
Simplify.
t = -24
I agree 3/5! I'm pretty sure, I haven't done this in forever so
The initial investment = $250
<span>annual simple interest rate of 3% = 0.03
</span>
Let the number of years = n
the annual increase = 0.03 * 250
At the beginning of year 1 ⇒ n = 1 ⇒⇒⇒ A(1) = 250 + 0 * 250 * 0.03 = 250
At the beginning of year 2 ⇒ n = 2 ⇒⇒⇒ A(2) = 250 + 1 * 250 * 0.03
At the beginning of year 3 ⇒ n = 3 ⇒⇒⇒ A(2) = 250 + 2 * 250 * 0.03
and so on .......
∴ <span>The formula that can be used to find the account’s balance at the beginning of year n is:
</span>
A(n) = 250 + (n-1)(0.03 • 250)
<span>At the beginning of year 14 ⇒ n = 14 ⇒ substitute with n at A(n)</span>
∴ A(14) = 250 + (14-1)(0.03*250) = 347.5
So, the correct option is <span>D.A(n) = 250 + (n – 1)(0.03 • 250); $347.50
