An art club sells 42 large candles and 56 small candles.
a. Write and simplify an expression that represents the profit.
expression for the profit: _(_-x)+_(_-y)
simplified expression for the profit: _______
b. A large candle costs $5, and a small candle costs $3. What is the club’s profit?
club's profit: $__

Answers

Answer:

Profit = $(700 - 42x - 56y)

Step-by-step explanation:

For large candles, the selling price is $10 and its making cost is $x.

So, by selling a large candle the profit is $(10 - x)

Again for small candles, the selling price is $5 and its making cost is $y.

So, by selling a small candle the profit is $(5 - y)

Therefore, in a sell of 42 large candles and 56 small candles the total profit will be, P = 42 (10 - x) + 56 (5 - y)

⇒ P = 420 - 42x + 280 - 56y {Applying distributive property}

⇒ P = $(700 - 42x - 56y) (Answer)

Step-by-step explanation:

Amanda makes 3 biscuits in 2 minutes. How many biscuits can she make in 30 minutes?

Answers

45 because 30 divided by 2 is 15 the 15 times 3

Amanda makes 45 biscuits in 30 minutes which is determined by the ratio.

What is Ratio?

A ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.

We have been given that Amanda makes 3 biscuits in 2 minutes.

Let the number of biscuits would be x

To determine the number of biscuits can she make in 30 minutes.

According to the given question, we can write the ratio as:

3 biscuits : 2 minutes = x biscuits : 30 minutes

⇒ 3 / 2 = x / 30

Apply the cross-multiplication operation

⇒ x = (30 × 3) / 2

Apply the multiplication operation

⇒ x = 90 / 2

Apply the division operation,

⇒ x = 45

Therefore, she makes 45 biscuits in 30 minutes.

Assuming the coordinates of the original image were (-5, 2), (2, 2), and (4, -3), then by dilating by two, it would be (-10, 4), (4, 4), and (8, -6)

Step-by-step explanation:

When dilating by a factor of n, you multiple both the x and y-coordinates by n, so -5*2 is -10 2*2 is 4, making the coordinate (-10, 4)
