Dylan and Ethan both leave the park at the same time, but in opposite directions. If Dylan travels 14 mph and Ethan travels 22 mph, how long until they are 324 miles apart?

9 hours

Step-by-step explanation:

Dylan: r=14, t=t, and d= d

Ethan: r=22, t=t, and d=324-d

d = rt = t=d/r

Dylan: t=d/14 and Ethan: t= (324-d)/22

t = t

d/14 = (324-d)/22 (cross multiplication)

22d = (14)*(324-d)

22d = 4536 - 14d

22d + 14d = 4536

36d = 4536

d = 4536/36

d = 126 miles

Dylan: 126/14= 9 and

Ethan= (324-126)/22 = 9

costs the what? what is the cost of the pants?

step-by-step explanation:

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.

40% of 10 = 4

4+10 = 14.

i believe the answer is c.
