First we have to see the formula of profit, which is
And it is given that profit should be atleast $150, that is
Let Ritax dollars per cake, so for 15 cakes, she charge 15x .
And she epent 30 dollars for 15 cakes.
So we will get
Adding 30 to both sides
Correct option is the second option .
You are asking for the solution, which here is the value of the variable g.
(-1/2)g = - 3 1/3
and this becomes
-g/2 = -10/3
Mult. both sides by -2 to obtain g = -20/3 (answer / solution)
Answer:
<h3> D) $276.26</h3>
Step-by-step explanation:
Deposited amount initially (P) = $250.
Rate of interest(r) = 2.5% compounded monthly = 0.025
Number of years (t) = 4.
Number of months in an year (n) = 12.
Formula for compound interest:
.
Plugging values in formula, we get

Answer: The percentage increase of Seraphina's speed is 15.52 %
Step-by-step explanation:
Total amount if time that Seraphina drove to visit her family is 2 hours.
For the first hour, she traveled at a speed of 58 miles per hour and in the second hour, she traveled at a speed of 67 miles per hour.
Increase in speed is the speed at which she travelled in the second hour - the speed at which she travelled in the first hour. It becomes
67-58 = 9 miles per hour
The percentage increase of Seraphina's speed is
(Increase in speed/ her speed in the first hour) × 100. This becomes
9/58 × 100
= 15.5172
15.52 %
Answer:
0(x-4)
Step-by-step explanation:
in my working system i mean just when i try on the place of 4 any number can be inserted
$5x-7=13x+17$,here both gives -22 as a result so
$6(x-4)$=6x-24 and to give the same result or 0
$6(x-4)$=0(x-any number )
