Answer:
<em>Mrs. Adams will earn $3,120 of interest at the end of year 8.</em>
Step-by-step explanation:
<u>Simple Interest</u>
In simple interest, the money earns interest at a fixed rate, assuming no new money is coming in or out of the account.
We can calculate the interests earned by an investment of value A in a period of time t, at an interest rate r with the formula:
Mrs. Adams deposited an amount of A=$12,000 into an account that earns an annual simple interest rate of r=3.25%. We must find the interest earned in t=8 years. The interest rate is converted to decimal as:
The interest is then calculated:
Mrs. Adams will earn $3,120 of interest at the end of year 8.
Expression for the number of tiles Bruce used : <u>5x+2</u>
Expression for the number of tiles Felicia used : <u>5x + 5</u>
<h3>Further Explanation </h3>One variable linear equation is an equation that has a variable and the exponent number is one.
Can be stated in the form:
or
ax + b = c, where a, b, and c are constants, x is a variable
We complete the introduction for the task
Bruce retiled his kitchen. Originally, he bought three boxes of tile with the same number of tiles in each. He ran out of tile and had to go back to get three extra boxes of tile. However, he only used two tiles from the last box to finish the job.
Felicia also retiled her kitchen. She bought five boxes of tile with the same number of tiles that were in each as Bruce’s boxes. She also ran out of tile. She had to go back to the store and get an extra five tiles to finish the job.
We can translate those in to expression of One variable linear equation (x = number of tiles)
- Bruce
He bought three boxes ⇒ 3x
He only used two tiles from the last box ⇒ 2x + 2
Total tiles of Bruce used : 3x+2x+2 = 5x+2
- Felicia
She bought five boxes ⇒ 5x
She get an extra five tiles to finish the job. ⇒ 5 tiles
Total tiles of Felicia used : 5x+5
