Answer:

The correct answer is A

Step-by-step explanation:

Here we start from the fact that there is a credit of 210, and each time she uses the club $15 will be deducted. if we take the x variable as the number of times she uses the club we have that the remaining credit is:

b=intitalCredit-x(value)\\b=210-15x

Sum : (5 x+1)

Term : 1, 5x and 3y

Product : 9(5x+1),5x and 3y

Factor : 5 and x, 3 and y, 9 and 5x+1

Quotient : \frac{9(5x+1)}{3y}

Coefficient : 5 is the coefficient of x and 3 is the coefficient of y.

Explanation:

The expression is \frac{9(5x+1)}{3y}

Sum: Sum is the result of addition of terms.

Thus, from the expression,

Sum = (5 x+1)

Term : A term is a single number or a variable or a number multiplied with a variable.

Thus, from the expression,

Term = 1, 5x and 3y

Product : Product is the result of multiplication of numbers.

Thus, from the expression,

Product = 9(5x+1),5x and 3y

Factor : The numbers that are multiplied is called a factor.

Thus, from the expression,

Factor = 5 and x, 3 and y, 9 and 5x+1

Quotient : Quotient is the result of dividing two numbers or variables.

Thus, the given whole expression is a quotient.

Hence, Quotient = \frac{9(5x+1)}{3y}

Coefficient : Coefficient of a variable is a number multiplied with a variable.

Thus, from the expression,

Coefficient : 5 is the coefficient of x and 3 is the coefficient of y.
