Answer:
Step-by-step explanation:
The profit function is:
Where
P is the profit
and
d is the number of units sold
Now, there is a 50% increase in number of units sold, so d will become:
50% = 50/100 = 0.5
d + 0.5d = 1.5d
So, we have to replace "d" with "1.5d" in the function, which makes it:
From the equations shown, last answer choice is correct.
Karen sent 25. Carlos sent 51. Also sent 17. The method is here if you want it. :)
Answer:P is the principal amount, $5000.00.
r is the interest rate, 3.5% per year, or in decimal form, 3.5/100=0.035.
t is the time involved, 5....year(s) time periods.
So, t is 5....year time periods.
To find the simple interest, we multiply 5000 × 0.035 × 5 to get that:
The interest is: $875.00
Step-by-step explanation:I=P×r×t

Answer:
54
Step-by-step explanation:
The ratio of 6 to 4 between the length and the with means that if the length was 6, the width would be 4.
We can represent this in a table:
Length Width
6 ⇒ 4
and we need to find the length for a picture frame that has a width of 36. If we represent the length of the picture frame by x, and we update the previous table:
Length Width
6 ⇒ 4
x ⇒ 36
The value of x (the length) can be found by the rule of three: Multiply the cross quantities in the last table ( 6 by 36) and divide the result by the remaining value (4).
We get the following for x:
x = 6*36/4
x= 216 / 4
x = 54
The length is 54.
Another way to find the result is:
The width of the frame (36) is 9 times more than the width that the ratio indicates (4). Because
4*9 = 36
thus, the same must be true for the relationship between the length in the indicated ratio and the length of the frame (9 times bigger):
6*9 = 54
we also get 54 as the result.
D and b maybe... (I’m not super sure though)
