Answer: 50% increase

Step-by-step explanation:

Think of 20 as 100%

Half of 20 is 10 which is 50% in this scenario.

30-20=10

This means that the price of the item increased by 50% or 10.

MissTica

Answer:

6 1/3

Step-by-step explanation:

3 times what equals 19 can be in the form of an equation as shown below. It shows that the value we are finding for is unknown, therefore it is a variable. A variable is the unknown value in an equation.

Equation: 3x = 19

With the equation in hand, we can now solve the problem easily.

3x = 19

Carry the 3 to the 19(Carry over the like terms across leaving the variable or the unknown)

x = 19÷3

x = 6.33333 or 6 1/3

To check if the answer was correct:

3 × 6 1/3 = 19

You regain the answer <em>19</em>
