Step-by-step explanation:
12n>135+4.50n
12(15)>135+4.50(15)
180>135+67.50
180>202.50
False. They will not make a profit since the cost is 202.50 versus the selling price 180
So here is the equation for the total amount of kids:
(16x+30)+ [(16x+30)+(5x-12)]

This is simplified to 37x+48 in terms of x using PEMDAS.
Answer:
Lets let l represent the length of the rectangle, and w represent the width.
The original area is l*w = lw

The new area is
2l * 2w = 4lw
So the new area is 4 times the original area.
