Set up an algebraic equation: b=cost of ball
1.10=1+b+b
1.10=1+2b
subtract 1 from both sides
.10=2b
divide by 2 on both sides
ball=5 cents
Circumference of a circle = pi x diameter
pi = 3.14
diameter = radius x 2
diameter = 10 x 2
diameter = 20
Circumference = 3.14 x 20
Circumference = 62.8 ft
607,99*1,085=659,66915 $ is the total cost
$480 since the question is just is how much would the would price be after the discount (discount)
