A ​used-boat dealership buys a boat for ​$2800 and then sells it for ​$4000. What is the percent​ increase?
Rudik [331]

Answer:

Step-by-step explanation:

percent increase = increase divided by original number x 100

                           

increase is the difference between the two numbers...

new number - original number.....4000 - 2800 = 1200

percent increase = (1200 / 2800) x 100

                            = 0.42857 (round to .4286) x 100

                             = 42.86 %.....if you need it rounded to the nearest percent, it      would be 43% increase

The equation 3x + 2 = 29 is modeled below.
DanielleElmas [232]

Answer:

Subtract 2 from both sides.

Step-by-step explanation:

Remember to do the opposite of PEMDAS. PEMDAS is the order of operation, and stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

> Also, note the equal sign, what you do to one side, you do to the other side of the equation.

First step is to subtract 2 from both sides of the equation:

3x + 2 (-2) = 29 (-2)

3x = 29 - 2

3x = 27

The second step is to divide 3 from both sides of the equation:

(3x)/3 = (27)/3

x = 27/3

x = 9
