Step-by-step explanation:
To find what percent of 80 is 28, you can use the formula:
Percent = (Part/Whole) x 100
In this case, the part is 28 and the whole is 80. Plugging these values into the formula:
Percent = (28/80) x 100 = 35%
So, Todd's mistake was not correctly calculating the percentage. The correct answer is that 28 is 35% of 80.
