Previous concepts
A hypothesis is defined as "a speculation or theory based on insufficient evidence that lends itself to further testing and experimentation. With further testing, a hypothesis can usually be proven true or false".
The null hypothesis is defined as "a hypothesis that says there is no statistical significance between the two variables in the hypothesis. It is the hypothesis that the researcher is trying to disprove".
The alternative hypothesis is "just the inverse, or opposite, of the null hypothesis. It is the hypothesis that researcher is trying to prove".

Answer:
0.5 represent the original 100% but we want to obtain a 75% aditional so we can find for the value x if interest and we got:
So we need to sell the fries ar 0.875$ if we want to obtain a 75% of margin
Step-by-step explanation:
For this case we know that the french fries cost $0.50 and we want to have a margin of 75% on the fries. So we can use the following proportional rule:
0.5 represent the original 100% but we want to obtain a 75% aditional so we can find for the value x if interest and we got:
So we need to sell the fries ar 0.875$ if we want to obtain a 75% of margin
