A=h(b+c)
A/h=b+c
b=(A/h)-c
Answer: b=(A/h)-c
You have to get from $30 to $21.75
21.75/30=0.725 x 100= 72.5% of the original price
<em>The result is -13</em>
<h2>
Explanation:</h2><h2 />
Here we have the following addition problem:

So let's solve this step by step:
Step 1. Perform two plus two.

So:

Step 2. Perform the subtraction.
Since the sign (-) accompanies 17 which is greater than 4, then we perform the subtraction and add the sign (-) to the result. So:

<em>Finally, the result is -13</em>

6²/2(3) +4
6²=36
2(3)=6
So now we have
36/6 + 4 which is 6 + 4 which is 10.
Answer:
x=5
Step-by-step explanation:
so after five months, the costs would equal each other.
Explanation:
You'd have to write equations for the price per month for each club.
Let x equal the number of months of membership, and y equal the total cost. Club A's is y=25x+40 and Club B's is y=30x+15.
Because we know that the prices, y, would be equal, we can set the two equations equal to each other.
25x+40=30x+15.
We can now solve for x by isolating the variable.
25x+25=30x.
25=5x.
5=x
After five months, the total cost would be the same.
