The Ortiz family is renting a hotel room for 5 days. They can spend S755 at most. There is a service fee of $30.
How many dollars can they spend at most on the per day rental fee including the $30 service fee?

The most they can spend on daily fees is $145

Step-by-step explanation:

Subtract one time service fee - $755-$30=$725

Divide the leftover by 5 for days stayed - 725/5=145

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
