Question

Mr. Williams is building a sand box for his children. It costs $228 for the sand if he builds a rectangular-sand box with dimensions 9 ft by 6 ft. How much will the sand cost if he decides to increase the size to 1312 ft by 9 ft?

Answer 1

first thing you want to do is create a proportion and isolate the unknown values by cross multiplying

$228/(9×6) = $x/(13.5×9)

after that, you will follow the order of operations.

Answer 2
