Jenny has twice as many cookies as Penny. Winnie has four more cookies than Jenny. If they have 44 cookies altogether, how many cookie does Penny have?
Write a number sentence
Penny has p cookies
Jenny has 2p cookies
Winnie has 2p+4 cookies
So, add them up:
p + 2p + 2p+4 = 44
THANK YOU
Let's use algebra to solve this problem.
Let's say the number of cookies that Penny has is "x".
According to the information given, Jenny has twice as many cookies as Penny, so Jenny has 2 * x = 2x cookies.
Winnie has four more cookies than Jenny, so Winnie has 2x + 4 cookies.
Together, they have 44 cookies, so we can write the equation as:
x + 2x + 2x + 4 = 44
Combining like terms, this equation simplifies to:
5x + 4 = 44
To solve for x, subtract 4 from both sides of the equation:
5x = 40
Finally, divide both sides of the equation by 5:
x = 8
Therefore, Penny has 8 cookies.
The number sentence to represent this is:
8 + 16 + 16 + 4 = 44
