Question

The quarterback for the Galactic Football team was playing in the Universe Bowl. On first down he rushed for 7 yards. On second down he was sacked for –5 yards. On third down he threw the ball for 6 yards. Which number sentence below correctly shows the total amount of yards he added?
Responses
A 7 – (–5) + 6 = 187 – (–5) + 6 = 18
B 7 – (–5) + 6 = 87 – (–5) + 6 = 8
C 7 + (–5) + 6 = 87 + (–5) + 6 = 8
D 7 + (–5) + 6 = 187 + (–5) + 6 = 18

Answer 1

To find the total amount of yards the quarterback added, we need to consider the plays:

1. First down: Rushed for 7 yards
2. Second down: Sacked for -5 yards (which means losing 5 yards)
3. Third down: Threw the ball for 6 yards

We can express this as a single equation:

Total yards = 7 (first down) + (-5) (sack) + 6 (third down).

This simplifies to:

Total yards = 7 - 5 + 6 = 8.

Thus, we need to find the correct number sentence representation from the options given.

Looking at the options:

A. 7 - (–5) + 6 = 18 (This is incorrect because it incorrectly presents the sack as adding to the yards).
B. 7 - (–5) + 6 = 8 (This is also incorrect for the same reason as A).
C. 7 + (–5) + 6 = 8 (This is correct).
D. 7 + (–5) + 6 = 18 (This is incorrect).

The correct answer is **C. 7 + (–5) + 6 = 8**.
