1 kilogram of baking soda costs $4.5
Step-by-step explanation:
To solve this problem, we will follow the steps bellow:
Using proportion;
Let x be the cost of 1 kg of baking soda
kilogram = $ 2
1 kilogram = x
Cross - multiply
× x = $2 × 1
× x = $2
= $2
Multiply both-side of the equation by 9
× 9= $2 × 9
At the left-hand side of the equation 9 will cancel-out 9, hence our equation becomes
4x = $18
Divide both-side of the equation by 4
= $
x = $4.5

Answer:
The third option: (f°g)(x)=1.07(0.65x)=06955x
Step-by-step explanation:
The reason I chose this is because 0.65x is the discount price. That's because 35% off is the same as 1.00-0.35 which equals 0.65. After that you would multiply that discount price by 1.07 because you want the 7% sales tax added on to the discount price. Therefore, I would choose the third option as my answer.
