The equation that can be used to find the area of the walkway is A = 3h+3b+9.
<h3>What is a rectangle?</h3>
A rectangle is a plane shape that has pair of opposite sides equal and parallel.
To find the equation that could be used to find the area of the walkway, we use the formula below.
Formula
- Area of the walkway(A) = Area of the swimming pool and the walk- area of the swimming pool
- A = [(h+3)(b+3)]-(hb)
- A = hb+3h+3b+9-hb
- A = 3h+3b+9.
Hence, The equation that can be used to find the area of the walkway is A = 3h+3b+9

for 3 hours, both studios charge the same amount.
<h3>
After how many hours are the total costs the same at both studios?</h3>
The cost equation for studio A is:
A(x) = 10.49 + 8*x
The cost equation for studio B is:
A(x) = 14.99 + 6.5*x
The cost will be the same when A(x) = B(x), then we just need to solve the linear equation:
10.49 + 8*x = 14.99 + 6.5*x
8x - 6.5x = 14.99 - 10.49
x = (14.99 - 10.49)/(8 - 6.5) = 3
This means that for 3 hours, both studios charge the same amount.

Answer:
The total cost is $82.51
Step-by-step explanation:
To find the total cost of the meal, first find the discount amount. We can get that by multiplying the discount percentage by the cost of the meal.
$78.58 * 15% = $11.79
Now we also need to find the tip amount, which we can calculate by multiplying the percentage by the overall cost.
$78.58 * 20% = $15.72
Now we take the amount of the meal and subtract the discount and add the tip.
$78.58 - $11.79 + $15.72 = $82.51
