Answer: The answer is 2x + 7.
Explanation: First, we need to add the numbers:
9x + 3 – 7x + 4
9x + 7 - 7x
And finally, we combine like terms:
9x + 7 - 7x
2x + 7
No she's not correct,,,
If the teas are $50 to start with 20% up from $50 is $62.50
if she counts down 20% down from that it wouldn't be $50 but be $40.
So she would not break even.
$33.33
20/9 = $2.22 per sheet
$2.22*15 = $33.33
