To do this, we must set up ratios:
Option One:
\frac{2.30}{250g}  \\  \frac{0.0092}{1g}  \\ 0.0092/g
The first options costs only $0.0092/gram (a fraction of a penny)!
Option Two:
\frac{3.40}{400g}  \\  \frac{0.0085}{1g} \\ 0.0085/g
The second option costs only $0.0085/gram (cheaper than option one)!
Option Three: 
This requires a little more work. First, we have to convert the grams into kilograms. For every 1 kg, there is 1,000 g. Therefore, 1,000g costs $5.65. Next, we set up the ratio as usual:
\frac{5.65}{1000g} \\  \frac{0.00565}{1g}  \\ 0.00565/g
The third option costs $0.00565/gram.

Therefore, option three is the cheapest! 

Hope this helps!

hoa [83]

We want to find the probability that Berenice gets all the answers correct.

<u>1 question:</u>

Each question has 4 options, each option has the same probability of being the correct option, so she has a 25% of<u> randomly selecting the correct option.</u>

Then the probability here will just be equal to the number of correct options (1) over the total number of options (4)

p = 1/4

2 questions:

We already know the probability for one question, then the probability of getting two questions correct will be equal to the <u>product of the individual probabilities</u> for each question:

p = (1/4)*(1/4 = 1/16

3 questions:

Similar approach as before:

p = (1/4)*(1/4)*(1/4) = 1/64

4 questions:

p =  (1/4)*(1/4)*(1/4)*(1/4) = 1/256
