Luigi is an urban planner. As an independent contractor, he charges a $140 fee plus $25 per hour for

Anuta_ua [19.1K]

Answer:

Function: $y=140+25x$

Amount earned for 10 hours of work: $\$390$

Step-by-step explanation:

Let be "x" the number of hours worked on a project and "y" the total amount Luigi charges for a project.

Based on the data given in the exercise, you can identify that:

$140 is a fixed amount.
For each hour worked on the project, Luigi charges $25. This can be expressed as: $25x$

Then, the total amount he charges for a project is the sum of $140 and $25x$ . This can be represented with the following function:

$y=140+25x$

To calculate the amount of money earned for 10 hours of work, you must substitute $x=10$ into the function and evaluate. Then:

$y=140+25(10)\\\\y=390$

Hannah earned $1536 in 8 years on an investment at a 4% annual simple interest rate. How much was Hannah’s investment? $4800 $30

Nonamiya [84]

Simple interest calculates interest on initial amount only. The investment by Hannah was : Option A: $4800

<h3>How to calculate simple interest amount if rate of interest is R% annually?</h3>

Suppose that the initial amount of investment is P

And the rate of simple interest is R% annually,

And the time of investment is T years.

Then, the amount of simple interest is calculated as:

$I = \dfrac{P \times R \times T}{100}$

For the given case, let the initial investment Hannah made was of $P

Then, the time of investment is T = 8 years, R% = 4%, and given that Hannah earned interest I = $1536

Putting values in the above formula, we get;

$I = \dfrac{P \times R \times T}{100}\\\\1536 = \dfrac{P \times 8 \times 4}{100}\\\\P = \dfrac{153600}{32} = 4800$

Thus,

The investment by Hannah was : Option A: $4800
