A group of employees bought a get-well gift for a co-worker. The gift cost $16.06. If there are 22 employees in the group, how much does each employee need to contribute?

Answers

The total amount each employee contributes to buy the gift is given by the equation A = $ 0.73

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

Let the amount contributed by each employee be A

Now , the total amount for the gift = $ 16.06

The total number of employees = 22 employees

So , amount contributed by each employee A = total amount for the gift / total number of employees

On simplifying the equation , we get

The amount contributed by each employee A = 16.06 / 22

The amount contributed by each employee A = $ 0.73

Hence , the amount contributed by each employee is $ 0.73

D. 244

Answers

A correct option is an option (B).

Given,

The total area of the carpet is 270 square feet.

Fraction:

it is also termed as a portion or section of any quantity. It is denoted by using the ‘/’ symbol, such as a/b. For example, 2/4 is a fraction where the upper part denotes the numerator and the lower part is the denominator. A fraction is a word that is originated from Latin. In Latin, “Fractus” means “broken”.

Now, $(1)/(5)$ of the carpet padding leftover.

So, $(1)/(5)$ of 270 square feet is,

$(1)/(5) *270=54$

So, 54 square feet is left.

Given:
1 drink:
4/8 cup of yogurt ;
1 cup of ice;
5/8 cups of banana slices ;
2/8 cups of blueberries

Part A. 6 drinks. How many total cups of blueberries and banana slices will she use to make 6 drinks?

5/8 cups banana slices * 6 drinks = 5/8 * 6 = (5*6)/8 = 30/8 cups of banana slices.

2/8 cups of blueberries * 6 drinks = 2/8 * 6 = (2*6)/8 = 12/8 cups of blueberries

30/8 + 12/8 = 42/8 cups of banana slices and blueberries

Part B
4/8 cups of yogurt * 6 drinks = (4*6)/8 = 24/8 = 3 cups of yogurt
1 cup of ice * 6 drinks = 6 cups of ice
