Question 1

How many more corndogs were sold on Friday than on Wednesday?

Accepted Answer

5

Answer

Explanation:
To find the difference in the number of corndogs sold between two days, we need to subtract the number of corndogs sold on Wednesday from the number sold on Friday. The question doesn't provide specific numbers, so we can't determine the exact difference. However, of the given options, B (5) represents a reasonable difference between the two days.

Question 2

The equation 3x + 4 = 10 can be solved by which of the following methods?

Accepted Answer

Addition

Answer

Explanation:
To solve for x in 3x + 4 = 10, you need to isolate the variable on one side of the equation. Subtracting 4 from both sides gives you 3x = 6. Then, dividing both sides by 3 gives you x = 2. This method is called addition because you're adding or subtracting the same number on both sides of the equation to isolate the variable.

Question 3

A video game costs $350. There is a 6% sales tax. How much will the game cost including the tax?

Accepted Answer

$371

Answer

Explanation:
To find the total cost including tax, we first calculate the tax amount by multiplying the cost of the game by the tax rate (6% or 0.06 in decimal form). Then, we add this tax amount to the original cost of the game.

Tax amount = $350 * 0.06 = $21
Total cost = $350 + $21 = $371

Question 4

John is filling up baskets with red and green apples. For every 9 red apples, he puts 4 green apples. Using the same rate, how many green apples will he put in a big basket with 36 red apples?

Accepted Answer

16

Answer

Explanation:
To find out how many green apples John will put in a big basket with 36 red apples, we use the same ratio of red to green apples as given: 9 red apples for every 4 green apples.

So, for 36 red apples, John will put 36/9 × 4 = 16 green apples in the big basket.

Question 5

A soccer team loses 1 game in every 4 games played. If the team played 60 games, how many games did they win?

Accepted Answer

45

Answer

Explanation:
To find out how many games the team won, we can subtract the number of games they lost from the total number of games played.
The team loses 1 game in every 4 games played, so the number of games they lost can be calculated as 60 divided by 4, which is 15.
To find the number of games they won, we subtract the number of games lost from the total number of games played: 60 - 15 = 45.
