Answer:
$ 637.17
Step-by-step explanation:
First, let's convert the interest per year (iy) to interest per month (im):
(1 + im)¹² = 1 + iy
(1 + im)¹² = 1 + 0.08
1 + im =
1 + im = 1.00643
im = 0.00643
im = 0.643%
The total amount (A) of an investment is:
Where R is the amount invested per month, and n the number of monthes. So:
10,000 = R*15.6943
R = $ 637.17
The graph is a quadratic function, and the equation of the function is C(x) = (x + 4)(x - 3)
<h3>How to determine the equation of the graph?</h3>
From the graph the x-intercepts are:
x = -4 and x = 3
Rewrite as:
x + 4 = 0 and x - 3 = 0
Evaluate the product of both equations
(x + 4) * (x - 3) = 0* 0
This gives
(x + 4)(x - 3) = 0
Express as a function
C(x) = (x + 4)(x - 3)
Hence, the equation of the function is C(x) = (x + 4)(x - 3)

Answer:
$180 was collected from Grade 9 students
Step-by-step explanation:
40% of 120 students is 48. This means that 48 students went. If half of these students paid half price, 24 students paid $2.50, and 24 students paid $5.00.
24 x 2.5 is 60
24 x 5 is 120
60 + 120 is 180, which is the total amount of money collected.
