John and Jivanti had 45 marbles together. After each lost 5, the product of their marbles was 124. This leads to a:
ARatio problem
BQuadratic equation
CLinear equation
DCubic equation
Answer & Solution
Correct answer: B. Quadratic equation
1. Let John have x, so Jivanti has 45 minus x.
2. The product of x minus 5 and 40 minus x is 124.
3. That product makes a quadratic.
