Question

At another sanctuary, the number of nesting turtles decreased by 10%. This year there were 234 nesting turtles. How many nesting turtles were at this sanctuary last year?

Answer 1

260 nesting turtles were at this sanctuary last year

Explanation:

Given:

The number of nesting turtles decreased = 10%

Number of turtles present in sanctuary this year = 234

To Find:

Number of nesting turtles present at this sanctuary last year= ?

Solution:

Let the number of nesting turtles present at this sanctuary last year be x

Then,

x- 10% of x = Number of turtles present in sanctuary this year

x- 10% of x = 234

`x- ((10)/(100) * x) = 234`

`x- ((1)/(10) * x) = 234`

`x- ((x)/(10)) = 234`

`(10x-x)/(10)=234`

`(9x)/(10)=234`

`9x=234* 10`

`9x=2340`

`x=(2340)/(9)`

x= 260
