Cody was 165 tall on the first day of school this year, which was 10% percent taller than he was on the first day of school last year. how tall was cody on the first day of school last year?

If we let x be Cody's height on the first day of the school last year then, his height on the first day of school this year can be expressed as,

     y = x + 0.10x

y is given to be 165. Substituting this to the given equation,

    165 = x + 0.10x

Simplifying,

    165 = 1.1x

The value of x from the equation is 150 ft. 

150 ft. 

Answer:

$4034.40

step-by-step explanation:

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
