Last year, the number of students enrolled in a school was 847. If this number increases by 9% the next year, how many students will there be?

Original 923.23

Can't have a fraction of a student, so I'd probably say 923

Step-by-step explanation:

Initial students: 847

Interest: 9%

You want 109%

Multiply: 847(1.09)

true

step-by-step explanation:

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
