Question

you read online that a 15ft by 20ft brick patio would cost about $2,275 to have professionally installed, estimate the cost of having a 19 by 21ft brick patio installed Round your answer to the nearest dollar $

Answer 1

$3028

Step-by-step explanation:

A 15ft by 20ft brick patio would cost about $2,275 to have professionally installed.

`\begin{gathered} \text{Area of the patio}=15*20 \\ =300ft^2 \end{gathered}`

Therefore, the unit cost (cost per ft²) will be:

`=(\$2275)/(300ft^2)\text{ }`

If the dimension of the new patio is 19ft by 21ft

`\begin{gathered} \text{Area of the new patio=}19*21 \\ =399ft^2 \end{gathered}`

Therefore, the estimated cost will be:

`\begin{gathered} =(\$2275)/(300ft^2)*399ft^2 \\ =\$3025.75 \\ =\$3028\text{ (to the nearest dollar)} \end{gathered}`
