Answer:
The correct answer is third option
(10x² - 4) - (7x² + 3)
Step-by-step explanation:
From the given option we get the correct answer is third option.
(10x² - 4) - (7x² + 3)
<u>Check the correct answer</u>
(10x² - 4) - (7x² + 3) = 10x² - 4 - 7x² - 3)
= 10x² - 7x² - 4 - 3 = 3x² - 7
Therefore the correct answer is third option
(10x² - 4) - (7x² + 3)
Distribute the 2 through the parentheses
on the right side of the equation.
2(y) is 2y and 2(2) is 4.
So the problem now reads 6 = 2y + 4.
Now we can subtract 4 from both
sides of the equation to get 2 = 2y.
Now divide both sides of the
equation by 2 and <em>1 = y</em>.

25% of 3,400 is 3,400/4=$850 spent rent
3,400-850= 2,550 remaining
30% of 2,550= 2550•0.3= $765 spent on transportation
