A video game that usually costs $30.65 is marked down 60%. Kelvin determined that the new price of the game would be $18.39. Loo
babunello [11817]

Answer:

Kelvin miscalculated and wrote 60 incorrectly.

He should have calculated $30.65 minus 60% instead of using 0.60.

The accurate final equation is:

$30.65 - 60% = 12.26

The total cost of 5 doughnuts and 6 cookies at a bakery is $11.95.The cost of each cookie is $0.95.Select the equation and its s
Zina [12379]

The formula representing this scenario is 5x+6(0.95)=11.95

The answer to this formula is x=1.25

Initially, you need to formulate the equation.

5x+6(0.95)=11.95

Next, simplify the expressions.

5x+5.7=11.95

Afterwards, subtract 5.7 from both sides.

5x=6.25

Lastly, divide both sides by 5

x=1.25

Which is the missing number: 9876, 6447, 2527, x?
Leona [12618]

This question reveals an intriguing pattern.

The rule or pattern to follow here is:

For the left side of the number compared to its predecessor: (First digit x Third digit + 1)

For the right side: (Second digit x Fourth digit -1)

For instance, consider 6447. Next, let's examine its previous number, 9876.

Now, 9\times 7+1=64 and

8\times 6-1=47

that's how we arrived at 6447

Next, for the third number, 2527, let's look at its previous number, 6447

Now, 6\times 4+1=25

and 4\times 7-1=27

that's how we reached 2527

Following the same reasoning, the missing number should be 534.

This conclusion came from applying the rule of the pattern as:

(2\times 2)+1=5

and

(5\times 7)-1=34

Thus, we derived 534.
