Final answer:
The exact percentage that Lester got correct on his math test cannot be determined with the information provided as the total number of questions is unknown. However, assuming the number of questions is 100, Lester's percentage score would be 78%, with the nearest given choice being 85%.
Step-by-step explanation:
To calculate the percentage score that Lester got correct on his math test, we can use the formula for percentage:
Percentage = (Number of Correct Answers / Total Number of Questions) × 100%
We do not have the total number of questions given in the question, so we'll assume that Lester got 78 questions correct out of 100 (which would be the simplest case and already expresses a percentage).
Applying the formula:
Percentage = (78 / 100) × 100% = 78%
Given the possible answers, there is none that exactly matches 78%. Therefore, it seems that we might be missing information about the total number of questions on the test to give a precise answer. But if we have to choose the closest option, it would be:
d) 85% as it is the nearest choice to 78%.
