2 circle graphs. A circle graph titled 2006. Top coats is 297, parkas is 210, jackets is 213, raincoats is 137, trench coats is 103. A circle graph titled 2007. Topcoats is 223, parkas is 210, jackets is 285, raincoats is 259, trench coats is 127.
Identify the percent increase in sales of parkas and the percent increase in sales of raincoats. Then find which percent of increase is greater and by how much greater it is than the other. (Round your answer to the nearest tenth.)
a.
Sales of parkas increased 65.2 percentage points faster than sales of raincoats.
b.
Sales of parkas increased 1.5 percentage points faster than sales of raincoats.
c.
Sales of raincoats increased 89.1 percentage points faster than sales of parkas.
d.
Sales of raincoats increased 49.0 percentage points faster than sales of parkas.

Answer 1

Parkas: (210 → 210) = 0% increase.
Raincoats: (137 → 259) increase = (259−137)/137 × 100% = 122/137 × 100% ≈ 89.1%.

Raincoats increased by 89.1 percentage points more than parkas, so choice (c).
