Answer:
The final price is $66.
Step-by-step explanation:
This question can be solved by a rule of three.
The initial price was of $120.
Initially, there was a discount of 15%. Then, there is another discount on the initial price. So the total discount is of 15+30 = 45%.
So the final price will be 100-45 = 55% = 0.55 of the initial price.
So
$120 - 1
x - 0.55

The final price is $66.
The correct answer is 6 grams of sugar
Hope this helped :)
Is this it or is there more to this question?
To solve 4(x-2)^2 = 16
divide each side by 4 to have (x-2)^2 = 4
take the square root of both sides
x-2 = -2 or x-2 = 2
add 2 to each side
x = 0 or x = 4
4 ( 0-2)^2 = 16
4 (-2)^2 = 16
4 (4) = 16 true
4 ( 4-2)^2 = 16
4 (2)^2 = 16
4 (4) = 16 true.
the values for x are 0 and 4.
