Pedro goes to the store and buys a binder, a folder, and a highlighter. The folder's cost is half the cost of the binder, and the highlighter's cost is $1.25 less than the 0binder. The total cost of the three supplies, with no tax, is $4.75. Write an equation to represent the situation. Show your work.

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

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

step-by-step explanation:

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58
