Use the formula s=32, 512(1.10)^t to calculate your salary after 2 years. Round your answer to the nearest dollar.

Answer:

s = $39,340

Explanation:

Note: I will use the symbol "n" instead of "t" in the solution.

The given formula is:

s = 32,512 * (1.1)ⁿ where "n" is the number of years.

We want to get the salary after 2 years. This means that we will substitute with n = 2 in the above equation and get the value of s.

This is shown as follows:

s = 32,512 * (1.1)²

s = $39,339.52 which is approximately $39,340

Using distributive property create an equivalent expression to 40+4x

evablogger [386]

Hi there!

To create an expression that uses the distribution property which can be simplified into 40 + 4x, we can find a factor between 40 and 4:

Since both 40 and 4 is divisible by 4,

40 / 4 = 10
4 / 4 = 1

We can put the 4 on the outside of the parenthesis, and put the quotients inside the parenthesis. And since the expression is in addition, we should include the addition symbol as the operation inside the parenthesis.

4(10 + x)
would be your answer.

Hope this helps!
