Question

Which situation can be represented by the equation -20 × 4 = -80?

A Rogelio is training for a marathon. For the last 4 days, he ran 20 miles each day. Roger ran 80 miles total over the last 4 days.
B Amira is at football practice. During the last 4 plays, the offense lost a total of 20 yards. During the entire football practice, the offense lost 80 yards total.
C Diana lost a total of 20 points on his last 4 math tests. He lost the same amount of points on each of the 4 tests. In total, Dwayne lost 80 points.
D Eli withdrew money from her bank account 4 times last month. Each time, she withdrew $20. In total, Eliana withdrew $80.

Answer 1

The correct scenario for the equation -20 × 4 = -80 is when the offense in a football game lost 20 yards in each of the last 4 plays, which totals a cumulative loss of 80 yards.

Step-by-step explanation:

The equation -20 × 4 = -80 represents a situation where a quantity is being multiplied by a negative number, resulting in a negative product. This type of equation can represent scenarios involving loss or negative growth over several instances.

The correct situation that can be represented by this equation is option B: Amira is at football practice. During the last 4 plays, the offense lost a total of 20 yards. During the entire football practice, the offense lost 80 yards total. This sits well with our equation as it implies a repeated loss over a period of time (× 4) to reach a total loss (-80).
