Answer: $1,907.63
Explanation:
It is stated in the problem that the brokerage fee is $450 plus 1.15% (meaning 1.15% of $126,750). Hence the brokerage fee is computed as follows
(Brokerage fee) = $450 + (1.15% of $126,750)
= $450 + (0.0115)($126,750)
= $450 + $1,457.625
= $1,907.625
Since there is no half cents today, we round-off the brokerage fee to the nearest cent. Hence the brokerage fee is $1,907.63.
Note: In the computation of brokerage fee, we need to change 1.15% to decimal.
y = 25x + 263 this equation represents how much money she will have, including her saving.
What is the linear equation?
A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are present. The variables in the above equation are y and x, and it is occasionally referred to as a "linear equation of two variables."
We have,
The saved amount of $263 by Jenna,
and also she earns $25 per day
if x represents the number of days she works,
and let's take y as the total amount she will have.
Then the equation becomes:
y = 25x + 263
Hence, y = 25x + 263 this equation represents how much money she will have, including her saving.

The difference between 1/8 and 6/10 = 0.475 , does this help?
Answer:
Option B.
Step-by-step explanation:
It is given that a graph titled Courses Completed versus Remaining Credits Needed to Graduate has courses completed on the x-axis and Credits need to graduate on the y-axis.
Points plotted are (4, 110), (8, 76), (16, 63), (20, 53), (24, 33).
Since, x-axis represents the courses completed, therefore the input, or independent variable is courses completed.
Since, y-axis represents the Credits need to graduate, therefore the output, or dependent variable is Credits need to graduate.
Therefore, the correct option is B.
