The population of a city is expected to increase by 7.5% next year. If p represents the current population, write an expression that represents the expected population next year?

Answers

Answer 1

Answer:

Answer: 1.75p

Step-by-step explanation:

Let 'p' represents the current population.

The increase in the population of the city =7.5%

Therefore, the expected population next year= Current population+75% of the current population

$=p+75\%\ of\ p\ \n=p+0.75p....\text{[convert percent into decimal]}\n=p(1+0.75).........\text{[take p as common outside]}\n=p(1.75)=1.75p$

Hence, the expected population next year= 1.75p

Answer 2

Answer: $p+7.5\%p=p+0.075p=\boxed{1.075p}$

Which options could be the next step in simplifying this expression? (18 + 23) + 7 Choose exactly two answers that are correct.
A. 18 + 30 (use the associative property)
B. 41 + 7 (use order of operations)
C. 30 + 25 (use the commutative property)
D. 25 + 30 (use the distributive property)

Answers

In adding, subtracting, multiplying anddividing numbers, always remember this rule: PMDAS (or parenthesis, multiply,divide, add, subtract). The P in PMDAS must come first. We must use an order ofoperations. In the problem given, (18 + 23) + 7, they must be added. However you have aparenthesis that has the numbers 18 and 23. You will add 18 and 23 first and then you will get 41. And so the answer is 41 + 7,letter B.
