Answer:
(a) The equation is .
(b) Trey gets approximately $8.29 for each hour of work.
Step-by-step explanation:
Given:
Number of hours Trey works = 7
Amount of money he put aside for mom = $2
Total Amount he keeps each day = $56
We need to find the amount he gets for each hour.
Let 'h' represent the amount (in dollars) Trey gets paid each hour.
Solving for part (a).
We need to write the equation to find the amount he gets paid for each hour.
Now we can say that;
Total Amount he keeps each day is equal to Number of hours Trey works multiplied by the amount he gets paid for each hour minus Amount of money he put aside for mom.
framing in equation form we get;
Hence the equation is .
Solving for part (b).
we need to solve the above equation to find the amount he gets paid for each hour.
On solving the equation we get;
Adding both side by 2 we get
Now Dividing both side by 7 using Division Property we get;
Hence Trey gets approximately $8.29 for each hour of work.
Using simple interest, it is found that $13,872 was loaned at 9%.
<h3>Simple Interest</h3>The amount of money after t years in simple interest is modeled by:
In which:
- P is the initial amount.
- r is the interest rate, as a decimal.
The interest earned is:
A bank loaned out $14000, in two parts, hence:
Part of it at the rate of 9% per year and the rest at 17% per year, hence:
The interest received in one year totaled $2000, hence:
Then:
Isolating as a function of
, then we can replace on the equation for the first interest.
Then:
$13,872 was loaned at 9%.
