Question 18 • LVA- Mathematical Modeling - Fall

Maria, Keisha, Jo, and Leah wear jerseys numbered 5, 8, 13, and 36, but not necessarily in that order. The girl wearing 8 has a better jumpshot than Maria or Leah. Jo’s jersey number is divisible by 6. The number of letters in one name is the same as her number. What number does each wear? (Make a table to help organize your information)

Answer
A
Maria - 5, Keisha - 8, Leah - 13, Jo - 36
B
Maria - 5, Leah - 8, Keisha - 13, Jo - 36
C
Jo - 5, Maria - 8, Leah - 13, Keisha - 36
D
Keisha - 5, Jo - 8, Maria - 13, Leah - 36

Explanation

Maria has 5 letters, so the clue about a name having the same number of letters as its jersey number gives Maria number 5. Jo’s number must be divisible by 6, so Jo wears 36. The girl wearing 8 cannot be Leah, since she is said to have a better jumpshot than Leah; therefore Keisha wears 8, leaving 13 for Leah. This matches choice A: Maria - 5, Keisha - 8, Leah - 13, Jo - 36.
