Sarah and her 4 friends share some cookies. If each person gets 3 cookies, how many cookies were shared? Write a mathematical equation that represents this situation.

Respuesta :

Let C represent the number of cookies shared.
Let 5 represent Sarah and her 4 friends.
C = 5 * 3
C = 15
So, since 5 friends got 3 cookies each, the total number of cookies shared is 15.
The equation will be: C = 5 * 3 or C = 5(3) 
:)

Answer:

The required equation is y=3x and number of cookies shared is 15.

Step-by-step explanation:

Given : Sarah and her 4 friends share some cookies. If each person gets 3 cookies.

To find : How many cookies were shared? Write a mathematical equation that represents this situation.

Solution :

Let y be the number of cookies shared and x be the number of person.

Each person gets 3 cookies.

i.e. 1 person = 3 cookies

So, x person = 3x cookies

Number of cookies shared is y=3x

Now, we have given x=5 (Sarah and her 4 friends)

So, Number of cookies shared is y=3(5)=15

Therefore, The required equation is y=3x and number of cookies shared is 15.
