Alexi’s restaurant bill is $58, and he wants to leave a 20 percent tip. Which expression represents the total amount that Alexi needs to pay? 58 dollars (0.20) + 58 dollars
58 dollars (0.20)
58 dollars (20)
58(20) + 58

The Answer is A

Step-by-step explanation:

58(0.2) = 11.6 + 58 = 69.6

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

the answer will be -6x^2 +46
