Equation:-
---------------
Total cost t =( r-$2)×3

Regular price r = (t+$2)/3

Total cost at last with the $10 per pair:-
–––––––––––––––––––––––––––––
Total cost if one pair is $10
=$10-$2=$8(hiking socks per pair price)
=$8×3=$24(3 pairs of hiking socks price)

Regular price r = (t+$2)/3

Total cost if one pair is $10
=$10-$2=$8(hiking socks per pair price)
=$8×3=$24(3 pairs of hiking socks price)

How many​ flowers, spaced every 4 ​in., are needed to surround a circular garden with a ​200-ft ​radius? Use 3.14 for π.
Masteriza [31]

Find the circumference of the circle:

Circumference = 2 x r x pi

Circumference = 2 x 200 x 3.14

Circumference = 1,256 feet.

4 inches/ 12 inches per foot = 0.333 ft.

Divide the circumference by the spacing:

1255/0.333 = 3,768

You will need 3,768 flowers
