Me! i don't understand how to do these type of questions and i need to do 4 of them!
ying ying wants to buy some petunias.
the table compares the number of petunias ying ying could buy and the money that would remain in her wallet (in dollars).
petunias money (dollars)
2 6.50
8 5.00
14 3.50
what is the price of one petunia?
$

$0.25

Step-by-step explanation:

Ok. You have to set up a system of equations that describe the situation and solve these equations. You are given some informations.

1. The price of a Petunia. Let' s give that a label and call it P.

2. The money left after the purchase. Let's call that number M.

3. The amount of money Ying Ying has in her wallet. Let's call that X.

Now you can form an equation: X = nP + M

Meaning: The money Ying Ying has in her wallet is equal to the value of n Petunias and $M left in her wallet. n and M are given in the table.

If Ying Ying buys 2 Petunias, she has $2 left in her wallet. If I have to describe this in an equation, I would write:

X = 2P + 6.5

All equations would look like this:

X = 2P + 6.5

X = 8P + 5

X = 14P + 3.5

Now you have 3 equations with only 2 unknowns, which can be solved for X and P.

X = 7 and P = 0.25

points are handed out whenever you post answers.

brainliest answers are handed out by the person asking the question, so whether your answer is picked depends entirely on whether the asker bothers to pick

if you're asking about your rank, it depends on having a certain number of points and a certain number of brainliest answers. for example, at the time of this writing, i have 44338 points out of 15000 needed for the next (nearly triple the requirement! ) but i only have 24 out of 50 required brainliest answers. this number decays, meaning after a certain amount of time (i think about a month), the total number of brainliest answers you've earned doesn't count toward this total. (i've been stuck at the same rank for a long

the lesson to learn here is that you shouldn't worry about points or rank. chances are, no matter how good an answer you may provide, your efforts will go mostly unnoticed unless you focus on the newest/most active questions that get posted.
