Regan sold 14 necklace and made a total of $210 if each necklace cost the same amount how much did one necklace cost 20 per necklace

We have been given that Regan sold 14 necklace and made a total of $210. Each necklace cost the same amount. We are asked to find the cost of one necklace.

To find the cost of one necklace, we will divide total cost by total number of necklaces as:

Therefore, the cost of one necklace is $15.

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.

i think the correct option is the second option.
