Peter is bored, so he decides to start coloring the outside sidewalk. would you believe every 15
minutes he goes through 14 pieces of chalk. that's a lot of chalkl after 3 hours his arms are so tired he quits.
how much chalk did peter use? explain

168 pieces

Step-by-step explanation:

15 mins = 14 pieces

1 hour = 56 pieces, therefore 3 hrs is 168 pieces

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
