Jay should have applied division operation first, then addition operation.
The abbreviation PEMDAS is used to indicate the sequence of steps to be taken when resolving expressions with multiple operations. P is for "parentheses," E is for "exponents," M is for "multiplication," D is for division, A is for addition, and S is for subtraction.
Given:
We have an expression,
3 × (3 + 12 ÷ 3) - 4.
In order to solve the problem,
we can use PEMDAS.
First, we solve parenthesis,
and division.
3 × (3 + 4) - 4.
Now,
3 × 7 - 4.
Now, multiplication,
21 - 4.
= 17
Therefore, the solution is 17.

Answer:
There will be 3472 cats in 10 years
Step-by-step explanation:
There were 3500 cats
The number of dogs in a city is declining at a rate of about 0.08% each year.
We are supposed to find the no. of cats in 10 years
Formula :
Where N(t) = Remaining cats after t days
= Initial population
r = rate of depreciation
t=time
So, No. of cats remained after 10 years =
Hence There will be 3472 cats in 10 years
