Based on the data, answer the questions.

A28%
B31%
C33%
D34% ✓ Correct
Correct answer: (D) 34% — The answer is about 34 percent.
Explanation
★The answer is about 34 percent.
★The 55AH sales were 108 thousand in 2015 and 145 thousand in 2021.
★The increase is 145 minus 108, which is 37 thousand.
★As a percent of 108, this is 37 divided by 108, times 100.
★That is about 34.25 percent, which rounds to 34.
★The other options do not match this value.
★So the answer is about 34 percent.
