The concession stand at the local high school sells pretzels and lemonade. The total cost of two pretzels and a lemonade is $5.75. The total cost of two lemonades is $0.25 more than the cost of a pretzel. What is the cost of a pretzel?

Answers

$2.35

Working
Let p represent the cost of pretzels and L the cost of a lemonade.
From the second paragraph,
2p+ L= 5.75

From the equation above, the cost of a pretzel p can be expressed as:
2p= 5.75 - L
p= 5.75/2 - l/2
The cost of two lemonades exceeds that of a pretzel by 0.25:
2 L= 5.75/2 -L/2+0.25

Solving this gives:
L=1.05

Then replace the value of L in p= 5.75/2 - L/2
This gives the value of a pretzel.

Final answer:

By using a system of equations, we can find that the cost of a pretzel is approximately $1.83.

Explanation:

This question can be solved using a system of linear equations. Let's define P as the cost of a pretzel and L as the cost of lemonade. So from the problem, we have 2 equations: 2P + L=$5.75 and L= P + $0.25.

Now, we can substitute the equation for L into the first equation to get: 2P + (P + $0.25) = $5.75, which simplifies to 3P + $0.25 = $5.75. Subtracting $0.25 from both sides gives 3P = $5.50. Dividing by 3 will then give the cost of a pretzel, so P = $5.50/3 = $1.83.

What is the answer to : 20 / 2(5+5)

Answers

Answer:

100

Explanation:

Before we begin, you should remember the order of operations from left to right:

1- Parentheses

2- Exponential

3- Division/multiplication

4- Addition/subtraction

Now , the given is:

$(20)/(2) * (5+5)$

We will start by resolving the brackets:

5+5 = 10

Therefore, the expression now is:

$(20)/(2) * 10$

Note that multiplication/division both have the same rank in the order of operations. This would mean that we will go from left to right and resolve whichever of them comes first.

In our expression, we can see that division comes first. So, we will start by division:

$(20)/(2) = 10$

The expression now became:

10 * 10

We will finally do the multiplication:

This would give us the final answer 100.

Combining all the above steps:

$(20)/(2) * (5+5) = (20)/(2) * 10 = 10 * 10 = 100$

Hope this helps :)

100

Further explanation

In the 1500s special rules of order of operations were issued. This sequence of work states which process takes precedence as the priority before other operations.

Operation priorities are as follows.

Parentheses (simplify in it)
Exponent
Multiplication or Division (from left to right)
Addition or Subtraction (from left to right)

Let's implement the rule.

$\boxed{ \ 20/2(5 + 5) \ } \rightarrow \boxed{ \ 20 / 2 (5 + 5) = \ ? \ }$

Inside the brackets, do the addition.

$\boxed{ \ 20 / 2 (10) = \ ? \ }$

Let us apply rule number 3 from the priority operation above. Operate on the left to right. We have to divide 20 by 2.

$\boxed{ \ 10(10) = \ ? \ }$

The continuous operation ends with multiplication.

$\boxed{ \ 10 * 10 = 100 \ }$

Thus, the answer is

$\boxed{ \ 20/2(5 + 5) \ } \rightarrow \boxed{\boxed{ \ 20 / 2 (5 + 5) = 100 \ }}$

Notes:

What if we don't follow the priority of the operation?

Look carefully at the following discussion.

At this crucial point:

$\boxed{ \ 20 / 2 (10) = \ ? \ }$

We decide to multiply 2 by 10, even though there are no parentheses from them, only parentheses for 10.

$\boxed{ \ 20 / 2 * 10 = \ ? \ }$

$\boxed{ \ 20 / 20 = 1 \ }$

Hence, $\boxed{ \ 20 / 2 (5 + 5) = 1 \ }$

That's what happens if we don't follow operating priorities.

Unless the problem like this:

$\boxed{ \ 20 / (2 (5 + 5)) = 1 \ }$

$\boxed{ \ 20 / (2 * 10) = 1 \ }$

$\boxed{ \ 20 / 20 = 1 \ }$

Thus, the difference must be considered. Consequently, obey the priority of the operation and look at the problem in detail.
