Question

The price of a technology stock has risen to $9.85 today. Yesterday's price was $9.72. Find the percentage increase. Round your answer to the nearest tenth of a percent.

Answer 1

percentage increase = 100*(new value - original value)/original value

in this case,
100*(9.85-9.72)/9.72
= 100*0.13/9.72
= 13/9.62
= 1.34

round to nearest 0.1%

answer is 1.3%
