Beth and carol has dinner at a cafe. the total bill was $14.50.beth’s meal cost $2.00 more than carol’s.

Assuming you want someones meal cost. Beth's - $8.25, Carol's - $6.25

Step-by-step explanation:

What I did might not make since. I took 14.50 - 2.00 = 12.50. Then 12.50 / 2 = 6.25. So Carols is $6.25 with Beth's being $2 more or $8.25.

(Beth)  b=$8.25

(Carol) c=$6.25

Step-by-step explanation:

1) Make Equations:      b+c=14.50        2+c=b

2) Substitute b Into The First Equation: 2+c+c=14.50

3) Simplify: 2c=12.50

4) Solve: c=6.25

5) Plug In c To The Second Equation: 2+6.25=b

6) Simplify: 8.25=b

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
