CorrectNot quiteAnswer C

Correct answer: C

Explanation

  1. A whole circle is 360°, so each 1% is 3.6°.

  2. Education: 15×3.6=54∘15 \times 3.6 = 54^\circ.

Worth noting

15° forgets to convert: 15% of a circle is 15% of 360°, not 15°. 45° multiplies 15 by 3 instead of by 3.6. 72° is the angle for savings (20%).
