Last year, sales at a book store increased from $5,000 to $10,000. This year, sales decreased to $5,000 from $10,000. What percentage did sales increase last year? What percentage did sales decrease this year?

Answers

Solution:

we are given that

Last year, sales at a book store increased from $5,000 to $10,000.

As we know that percentage increase is given by the formula

Percentage increase $=(change)/(Initial)*100$

Substitute the values we get

Percentage increase $=(10000-5000)/(5000)*100$

Percentage increase $=(5000)/(5000)*100=100$ %.

This year, sales decreased to $5,000 from $10,000.

Percentage Decrease $=(change)/(Initial)*100$

Substitute the values we get

Percentage Decrease $=(10000-5000)/(10000)*100$

Percentage Decrease $=(5000)/(10000)*100=50$ %.

Answer:

100%, 50%

Step-by-step explanation:

a company pays its employees a base salary of $1000 every other week. plus $30 for each sale. How many sales did the employee have if the paycheck is $1540

Answers

F(x)= 1000+30x
1540=1000+30x
1540-1000=30x
540/30=x
X=18
18 sales

The correct answer is 18 sales. 18 x 30 + 1000 = 1540.

Log (base 8) 2 +log (base 8) 4x^2 =1

Answers

Log (base8) 2 = 1/3

Log (base 8) (4x^2) + Log (base 8) 4 + 2Log (base 8) x = 2/3 + 2 Log (base 8) x

1/3 + 2/3 + 2 Log (base 8) x = 1

2 Log (base 8) x = 0

Log (base 8) x = 0

x = 8^0

x = 1.

4x+17/18-13x-2/17x-32+X/3= 7x/12-x+16/36

Answers

Answer:To solve the equation 4x + 17/18 - 13x - 2/17x - 32 + x/3 = 7x/12 - x + 16/36, we can follow these steps:

1. Combine like terms on each side of the equation.

On the left side, we have 4x - 13x + x/3. Simplifying this, we get -8x + x/3.

On the right side, we have 7x/12 - x + 16/36. Simplifying this, we get -5x/12 - x + 4/9.

2. Get rid of any fractions by multiplying each term by the least common denominator (LCD).

The LCD of 3, 12, and 36 is 36. Multiply each term on both sides of the equation by 36 to eliminate the fractions.

3. Simplify and combine like terms.

On the left side, we have -8x + x/3, which becomes -24x + x^2/3 after multiplying by 36.

On the right side, we have -5x/12 - x + 4/9, which becomes -15x - 3x + 16 after multiplying by 36.

4. Move all terms to one side of the equation.

Combining like terms, we get -24x + x^2/3 = -18x + 16.

5. Multiply the entire equation by 3 to eliminate the fraction.

This gives us -72x + x^2 = -54x + 48.

6. Move all terms to one side of the equation again.

Combining like terms, we get x^2 + 18x - 48 = 0.

At this point, the equation is a quadratic equation. To solve it, we can either factor or use the quadratic formula.

A small grill can hold two hamburgers at a time. If it takes 5 minutes to cook one side of a hamburger, what is the shortest time needed to cook both sides of five hamburgers?

Answers

If you were to grill two hamburgers at the same it would take 5 minutes to grill one side of 2 hamburgers and ten minutes to grill 2 ham burgers on both sides. So 10 minutes would make two hamburgers while 20 minutes will cook 4 hamburgers than add and extra 10 minutes to cook the last hamburger on both sides.
10 minutes = 2 both side cooked hamburgers
+
10 minutes = 2 both side cooked hamburgers
+
an extra 10 minutes = another both side cooked hamburgers since we only need five
=
30 minutes in minimal time to cook five hamburgers

What is the slope of the line 4x + 6y = 12

Answers

I believe its going to be (3,2) because you take 12 and divide it by 4 which gives you your x value of 3 then you take 12 and divide it by 6 which gives you your y value of 2

4x+6y=12
-4x -4x
6y=-4x+12
-6 -6

Answer: Y= -4x+12
