To calculate the total amount Rebecca paid for the video game including sales tax, we need to add the sales tax to the original price of the game.
Sales tax amount = 7% of $30 = 0.07 * $30 = $2.10
Total amount paid = $30 + $2.10 = $32.10
Therefore, Rebecca paid $32.10 for the video game including sales tax.
The correct answer is:
$32.10
Sales tax amount = 7% of $30 = 0.07 * $30 = $2.10
Total amount paid = $30 + $2.10 = $32.10
Therefore, Rebecca paid $32.10 for the video game including sales tax.
The correct answer is:
$32.10

To simplify the given expression, we can combine like terms.
(5 + 38y) + (14y - 2)
= 5 + 38y + 14y - 2
= (38y + 14y) + (5 - 2)
= 52y + 3
Therefore, the expression can be written as:
52y + 3
The correct answer is:
52y + 3
(5 + 38y) + (14y - 2)
= 5 + 38y + 14y - 2
= (38y + 14y) + (5 - 2)
= 52y + 3
Therefore, the expression can be written as:
52y + 3
The correct answer is:
52y + 3

To simplify the given expression, we need to distribute the negative sign to both terms inside the parentheses.
(7x + 6) - (8 + x)
= 7x + 6 - 8 - x
= 7x - x + 6 - 8
= 6x - 2
Therefore, the simplified expression is:
6x - 2
The correct answer is:
6x - 2
(7x + 6) - (8 + x)
= 7x + 6 - 8 - x
= 7x - x + 6 - 8
= 6x - 2
Therefore, the simplified expression is:
6x - 2
The correct answer is:
6x - 2

To simplify the given expression, we need to combine like terms within each parentheses and then simplify further.
(7x - 2) - (0.04x - 3 + 0.2x)
= 7x - 2 - 0.04x + 3 - 0.2x
= 7x - 0.04x - 0.2x - 2 + 3
= 7x - 0.24x - 2 + 3
= 7x - 0.24x + 1
Therefore, the simplified expression is:
7x - 0.24x + 1
The only equivalent expression from the given options is:
(7x - 2) - (0.24x - 3)
None of the other options provided are equivalent expressions.
(7x - 2) - (0.04x - 3 + 0.2x)
= 7x - 2 - 0.04x + 3 - 0.2x
= 7x - 0.04x - 0.2x - 2 + 3
= 7x - 0.24x - 2 + 3
= 7x - 0.24x + 1
Therefore, the simplified expression is:
7x - 0.24x + 1
The only equivalent expression from the given options is:
(7x - 2) - (0.24x - 3)
None of the other options provided are equivalent expressions.
