Answer:

The original price was $43.50

Step-by-step explanation:

Let

x ----> the original price of a video game

we know that

1) The price of a video game increases by 20%

so

100\%+20\%=120\%=120/100=1.20

The final price is equal to the original price multiplied by 1.20

so

1.20x

2) The price of a video game decreases by 10%

so

100\%-10\%=90\%=90/100=0.90

The final price is equal to the price at this moment multiplied by 0.90

so

0.90(1.20x)=1.08x

we have that

1.08x=46.98

solve for x

x=46.98/1.08\\x=\$43.50

Write a 3-digit number that is divisible by both 3 and 4. Explain how you know this number is divisible by 3 and 4.
Alexeev081 [22]

Answer:

let us assume the 3 digit number be 984

To check weather the number is divisible by 3 and 4 then when should know the divisibility rule of 3 and 4.

A number is said to be divisible by 3 when the sum of each digit of the number is divisible by 3. Example 9+8+4 = 21 is divisible by 3 hence the number is divisible by 3.

A number is said to be divisible by 4 when the last two digit is divisible by 4 like 84 is divisible by 4 hence 984 is divisible by 4.
