You read online that a 15 ft by 20 ft brick patio would cost about $2,275 to have professionally installed.
Estimate the cost of having a 18 by 22 ft brick patio installed.

$3003

Step-by-step explanation:

Installation cost of 15 ft * 20 ft brick patio = $2275

In other words, Installation cost of 300 square feet brick patio = $2275

So the cost of 1 square feet brick patio =

= $7.5833

Now to install a 18 ft * 22 ft patio, its area = 396 square feet

Cost of installing a 396 square feet patio = 396 * $7.5833 = $3003 ( approx)

This is cost that needs to be paid for the extended patio.

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
