There were 3,260 visitors to a county fair on Friday. On Saturday the number of visitors to the fair increased by 15%. Fair organizers had projected a 20% increase in attendance on Saturday. By how many visitors did Saturday's actual attendance fall short of the projected attendance?

163

Step-by-step explanation:

Given the following :

Number of visitors on Friday = 3,260

Number increased by 15% on Saturday

Projected percentage increase on Saturday = 20%

Actual percentage increase in number of visitors = 15%

Number of visitors on Saturday :

(100 + 15)% × 3260

115% * 3260

(115/100) * 3260

= 3749 visitors

Projected percentage increase = 20%

Projected number:

((100 + 20)% * 3260

120% * 3260

(120/100) * 3260

= 3912

Difference : (3912 - 3749) = 163
