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

Answer:

260 nesting turtles were at this sanctuary last year

Step-by-step 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

$x- (\frac{10}{100} \times x) = 234$

$x- (\frac{1}{10} \times x) = 234$

$x- (\frac{x}{10}) = 234$

$\frac{10x-x}{10}=234$

$\frac{9x}{10}=234$

$9x=234\times 10$

$9x=2340$

$x=\frac{2340}{9}$

x= 260
