An appliance repairman charges $50 for service calls plus $25 per hour for labor. Write and solve an equation to determine how much he would charge for a 3.5 hour service call.

C = $137.50

Step-by-step explanation:

Okie dokie, so we already know he charges $50 just for a service call, plus 25 per hour, so let's say the total charge is C.

Now, let's make an equation:

C = 50 + 25(3.5)

Now, multiply 25 and 3.5 together:

C = 50 + 87.5

Now we just combine the like terms:

C = $137.5

Hope this helps :)

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

yo answer should be 6 if im not mistaken
