Carpet costs $12 per square yard. How much will it cost to carpet a room that is 180 square feet?

Answers

Converting units from feet to yards is easy. However, it becomes tricky when converting square yard to square feet but it is easy if you get the gist of it. Simply square both sides of the conversion:

Since 3 feet = 1 yard
(3 feet)^2 = (1 yard)^2
9 feet^2 = 1 yard^2

In the same way, if you want to convert from cubic feet to cubic yard, simply cube (raise to the power of 3) both sides. :)

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Ben has 9 packs of balloons. He has 54 balloons in all. The number of the ballons will be calculated as,

Number = Total balloons / Packs of ballons

Number = 54 / 9

Number = 6

Hence, the number of balloons in each pack will be 6. The correct option is A.
