Answer 1

Answer:

The percentage decrease in the number candid student pictures for the yearbook from 2015 to 2016 is approximately 9.3 percent

Step-by-step explanation:

The given data can be presented as follows

Year           ${}$                      Number of Photos

2015           ${}$                      236

2016           ${}$                      214

The percentage decrease in the number of candid pictures is give by the following formula

$Percentage \ Decrease = \dfrac{Original \ Value- New \ Value}{Original \ Value} \times 100$

Where;

Original value for the number of pictures = 236

New value for the number of pictures = 214

Substituting the values into the equation for the percentage decrease gives;

$Percentage \ Decrease = \dfrac{236- 214}{236} \times 100 = \dfrac{550}{59} \ percent\approx 9.3 \%$

The percentage decrease is approximately 9.3 percent.
