The school is selling potted plants as a fundraiser. kara sold 12 ferns and 8 ivy plants for $260. paul sold 15 ivy plants and 6 ferns for $240. what is the selling price of each plant?

Fern = $15

Ivy= $10

Step-by-step explanation:

Let f = ferns and v = ivy

12f + 8v = $260 1

6f + 15v = $240 2

Using elimination method

multiply eqn 1 by 15 and eqn 2 by 8

180f +120v = 3900

48f + 120v = 1920

Subtracting

132f = 1980

f = $15

From eqn 1

12*15 + 8v = 260

180 + 8v = 260

8v = 80

v = $10

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
