Which answer describes the simpler problems that could be used to solve this story problem? Alice made $1,245 one summer. She spent $120 on a new bike. She spent twice as much on a plane ticket to New York as she spent on her bike. How much money did Alice have left?

A.
Calculate the cost of the plane ticket. Add that number to the cost of the bike. Subtract the sum from $1,245.

B.
Calculate the cost of the plane ticket. Multiply it by 2. Add the cost of the bike. Subtract the sum from $1,245.

C.
Calculate how much more Alice spent on the plane ticket than the bike. Multiply this amount by the number of plane tickets. Add the 2 amounts.

D.
Calculate how much more Alice spent on the plane ticket than the bike. Multiply this amount by the number of plane tickets. Subtract this number from $1,245.

Answer:

to be honest i do not know this answer but i assume that it is big like by a lot

Step-by-step explanation:

What makes a NUMBER rational is the ability to have a perfect square root, cube root, or have these components: Perfect square/cube, whole number, repeating (pattern) decimal, termination decimal, and I think one more that I can't remember.

The properties of the rational exponents are given and a rational equation is of the form b = aˣ

What are the laws of exponents?

When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1. Negative exponents are the reciprocals of the positive exponents.

The different Laws of exponents are:

mᵃ×mᵇ = mᵃ⁺ᵇ

mᵃ / mᵇ = mᵃ⁻ᵇ

( mᵃ )ᵇ = mᵃᵇ

mᵃ / nᵃ = ( m / n )ᵃ

m⁰ = 1

m⁻ᵃ = ( 1 / mᵃ )

Given data ,

Let the rational exponent equation be A

Now , the properties of the exponent equations are

mᵃ×mᵇ = mᵃ⁺ᵇ

The powers of the exponents are added together

mᵃ / mᵇ = mᵃ⁻ᵇ

The powers of the exponents are subtracted together

( mᵃ )ᵇ = mᵃᵇ

The powers of the exponents are multiplied together

mᵃ / nᵃ = ( m / n )ᵃ

m⁰ = 1

Any number raised to the power of 0 is 1

m⁻ᵃ = ( 1 / mᵃ )

Hence , the exponents are solved

Final answer:

Rational exponents have properties that help to simplify expressions and solve mathematical problems. These properties include the product rule, the quotient rule, and the power rule. Utilizing these rules, especially in scientific notation, helps provide concise computations for very large or small numbers.

Explanation:

Properties of Rational Exponents

The properties of rational exponents play a key role in simplifying expressions and solving mathematical problems. Here are three key properties:

• Product Rule: When you multiply two numbers with the same base, you should add the exponents. This is expressed as: a^m * a^n = a^(m+n).
• Quotient Rule: When you divide two numbers with the same base, you should subtract the exponents. This rule is reflected in: a^m / a^n = a^(m-n).
• Power Rule: When you raise a power to a power, you should multiply the exponents: (a^m)^n=a^(mn).

These properties are crucial for solving problems. For example, scientific notation, which is used to represent very large or small numbers, employs these properties of exponents. In scientific notation, numbers are expressed as a product of a digit term and an exponential term. This method is useful for making computations convenient and precise.
