4) 8/6.4=1.25 (Scale factor)
for y: 14/1.25=11.2

SVEN [57.7K]

Answer:

The percent decrease is approximately 10.75\%

(Don't know what you are expected to round to.)

Step-by-step explanation:

Percent change can be calculated by doing:

\frac{\text{original}-\text{new}}{\text{original}}

Then you multiply the result to covert it to a percentage.

Let's use this formula:

\frac{5831 \text{thousand}-5204 \text{ thousand }}{5831 \text{thousand}}

\frac{\text{thousand}}{\text{thousand}} \cdot \frac{5831-5204}{5831}

\frac{5831-5204}{5831}

\frac{627}{5831}

0.1075 approximately

Now the answer as a percent is 10.75\% approximately.

The percent decrease is approximately 10.75\%
