8 Children divided 32 apples. Kitty took 1 apple, Mary took 2, Sherrie took 3 and Caroline took 4. Bob SMITH took as many as his sister, Ken Brown took twice as many as his sister, Jim Jones took 3 times as many as his sister and Tom Robinson took 4 times as many as his sister. What is the last name of each of the 4 girls??
Yeah.... um i need help with that too. My brother is in 11th grade and he can't do it so....
To find the last names of the four girls, let's analyze the given information step by step.
First, let's assign variables for the names of the four girls.
Let:
- Kitty's last name be X
- Mary's last name be Y
- Sherrie's last name be Z
- Caroline's last name be W
We know that Kitty took 1 apple, so X = 1.
Mary took 2 apples, so Y = 2.
Sherrie took 3 apples, so Z = 3.
Caroline took 4 apples, so W = 4.
Now let's consider the information about the boys and their sisters:
Bob Smith took as many apples as his sister. Since his sister's name is Z and Sherrie took 3 apples, Bob Smith also took 3 apples. So Bob Smith's last name is Smith.
Ken Brown took twice as many apples as his sister. Since his sister's name is W and Caroline took 4 apples, Ken Brown took 2 x 4 = 8 apples. So Ken Brown's last name is Brown.
Jim Jones took three times as many apples as his sister. Since his sister's name is X and Kitty took 1 apple, Jim Jones took 3 x 1 = 3 apples. So Jim Jone's last name is Jones.
Tom Robinson took four times as many apples as his sister. Since his sister's name is Y and Mary took 2 apples, Tom Robinson took 4 x 2 = 8 apples. So Tom Robinson's last name is Robinson.
Therefore, the last names of the four girls are:
- Kitty's last name is X = Unknown
- Mary's last name is Y = Unknown
- Sherrie's last name is Z = Smith
- Caroline's last name is W = Brown
