The sales tax is 3.49 I think
The bottom trapezoid is
(1/2) * h * (b2 + b1) =
(1/2)*11 * (31+25)
(1/2) * 11 * 56
308
The top parallelogram is
b * h = 12 * 14 = 168
308 +168 = 476 ft^2
Letter B
A. 1 1/2 is equal to 1.5, so this is true
B. 3/4 is equal to 0.75 and 7/8 is equal to 0.875, this is true
C. -1.5 is less than both -1 and 1.5, this is false
D. 0.01 is less than 0.1, this is true
So the answer to your question is C
Area of original poster=80
Area of enlarged poster=320
The area of the enlarged is 4x larger than the original
I think this is how you would do it but good luck
