Since 81 will be 27 percent of the total number of magazines you will find "81 is 27 percent of what number?"
81 is 27 percent of 300.
Therefore, her class hoped to sell 300 magazines in total!
Suppose there is a rectangle with a width and length of x and y. The area would be xy.
A rectangle with width and length 2x and 2y would have an area of 4xy.
In essence, when you multiply the lengths by 2, the area multiplies by 2 SQUARED.
4(4(x+3)) = 16(x+3).
The ratio will be the same for any value of x because the area is still being multiplied by the same 2².
Answer: D. None of the above
