Taxis usually charge a fee on top of the per-mile charge. In this case, the taxi charges $3 as a set fee and $0.80 per mile traveled. The function y=0.8x+3 is used to represent the total cost of a ride.

$12.3

Step-by-step explanation:

Given data

We are given that the function for the charge is expressed as

y=0.8x+3

Where y is the total cost for a ride

X is the distance of the ride

Say x= 12 miles

Hence the total cost of the ride is

Y= 0.8*12+3

Y= 9.6+3

Y= $12.3

Hence a 12 miles Distance will cost $12.3

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
