What is 8.154 rounded to 2 decimal places?" is the same as asking, "What is 8.154 rounded to two decimal points?" or "How to round 8.154 to two decimal places."

The main point is that you want to round 8.154 to two digits or places after the decimal point. Thus, we want to eliminate the last digit in 8.154. To eliminate the last digit in 8.154, we use the following Two Decimal Places Rules to get the answer:

Two Decimal Places Rule #1: If the last digit in 8.154 is less than 5, then remove the last digit.

Two Decimal Places Rule #2: If the last digit in 8.154 is 5 or more and the second to the last digit in 8.154 is less than 9, then remove the last digit and add 1 to the second to the last digit.

It cost $5 for his brother's ticket.

Step-by-step explanation:

Let,

Micheal's ticket price= x

His brother ticket price = y

According to given statement;

x+y=12    Eqn 1

y = x-2    Eqn 2

Putting value of y from Eqn 2 in Eqn 1

x+(x-2)=12\\x+x-2=12\\2x=12+2\\2x=14\\

Dividing both sides by 2;

\frac{2x}{2}=\frac{14}{2}\\x=7

Putting x=7 in Eqn 2

y=7-2\\y=5

It cost $5 for his brother's ticket.

Answer:

  D)  3.57%

Step-by-step explanation:

The percentage change is given by ...

  percent change = ((new value) -(old value))/(old value) × 100%

  = (3.19 -3.08)/3.08 × 100% = 0.11/3.08 × 100% = (11/3.08)% ≈ 3.57%

__

When dealing with percentages, you need to be clear about what number represents 100%, the reference value against which errors or changes are measured. Here, it is the π of the mug, 3.08.
