Answer: $225
Step-by-step explanation:
Let the value of the bond at the purchase price be x.
Based on the information in the question, the equation to solve the question will be:
x + (8% × x) = $243
x + (8/100 × x) = $243
x + 0.08x = $243
1.08x = $243
x = $243/1.08
x = $225
Taylor's mom purchased the bond at $225
(8/4) = (10/x)
8x = 4 x 10
8x= 40
x = 40/8
x=5
It will take 5 hours.
Answer:
(a) 
(b) 
(c) Maximum area
square meters
Step-by-step explanation:
(a)
Given:
Total length for fencing = 160 m
Width of the rectangle =
m.
Let the other length of the rectangle be
m.
Then, from the figure,

Now, area of a rectangle is equal to the product of its length and width.
So, area is, 
(b)
Given:

For maximum area, derivative of area with respect to
must be 0.
So, 
Therefore, for maximum area,
.
(c)
Given:

Maximum area occurs at
. Plug in 40 for
in
expression. This gives,
Maximum area is,

Therefore, maximum area is 3200 square meters.
Answer:
B, H
Step-by-step explanation:
The electrician charges 45 dollars per hour and 30 at the beginning. We are multiplying the hours, h, by 45 to get 45h. We add 30 to get C=45h+30
Jerome will always earn 75 dollars, but he also gets 10 percent commission, which is 0.10.
