Question

During the summer between tenth grade and eleventh grade, a student experienced a growth spurt and grew from 67 inches to 72 inches. By what percent did the student's height increase?

Answer 1

about 7.5%

Explanation:

The percentage change is calculated from ...

pct change = ((new value) - (old value))/(old value) × 100%

= (72 -67)/72 × 100%

≈ .07463 × 100%

≈ 7.5%

The student's height increased by about 7.5%.
