Answer:
5x+56
Step-by-step explanation:
5x+8(5+2)
5x+8(7)
Find the rectangle area
A = 8*4 = 32 in²
Find the height of trapezoid
8-4 = 4 in
Find the area of trapezoid
(5,3+8)*4/2 = 13,3*4/2 = 53,2/2 = 26,6 in²
Find the figure area
26,6+32 = 58,6 in²
The total will be $19.72 with 20% so she will get back $30.28
First divide 6/(6+6+8) =0.3
Then multiple it by 100 to get the probability percentage 30%
