Final answer:
The correct ratio of chicken to beef tacos that Sam bought is 1:3, meaning for every chicken taco there are three beef tacos. However, there's a discrepancy with the cost of one beef taco, as the calculated cost of about $0.33 per taco does not match any of the options provided.
Step-by-step explanation:
To determine the ratio of chicken to beef tacos that Sam bought, we compare the number of each type of taco. Sam bought 4 chicken tacos and 12 beef tacos. The ratio of chicken to beef tacos is simply 4:12, which can be simplified by dividing both numbers by 4, resulting in a 1:3 ratio. This means that for every chicken taco, there are three beef tacos.
Next, to find out the cost of one beef taco, we take the total amount Sam paid for the beef tacos and divide it by the number of beef tacos. Sam spent $4.00 for 12 beef tacos, so if we divide $4.00 by 12, we get approximately $0.33 per beef taco. However, since this is not one of the options provided, let's look again at the options.
Reviewing the question, it appears that the options may be mistakenly given, as none of the costs align with the calculated cost per beef taco. Thus, none of the given options correctly state the cost of one beef taco based on the information provided in the question. However, the correct ratio is among the options given, which is 1:3.
