(A) The print area is 4/10 × 100% = 40% of the total, so the ad area is ...
... 100% - 40% = 60% of the print area
(B) News : Ads = (40%) : (60%) = 2 : 3
Price of one citron = 5 units
Price of one fragrant = 5/7 units = 0.71 units
Further explanation:
Let x be the price of one citron and
y be the price of one fragrant
Then according to given statement
10x+7y = 55 Eqn 1
7x+10y = 64 Eqn 2
Multiplying equation 1 by 7
This will be equation 3.
Multiplying equation 2 by 10
This will be equation 4.
Subtracting equation 3 from equation 4
So,
Price of one citron = 5 units
Price of one fragrant = 5/7 units = 0.71 units

Hello! :)
Answer:
--------------------------------------------------------------------------
An angle bisector divides an angle in half, therefore:
m∠VUW ≅ m∠WUT
Set the expressions equal to each other:
4x + 6 = 6x - 10
Subtract 4x from both sides:
6 = 2x - 10
Add 10 to both sides:
16 = 2x
Divide 2 from both sides:
x = 8.
Substitute in the value of "x" into the equation for ∠WUT:
6(8) - 10 = 48 - 10 = 38°.
