Answer:
Alexander is incorrect because the expressions are not equivalent.
Step-by-step explanation:
If the expression is evaluated for any value of x, y; the result will not be same.
For instance, let assume x = 1 and y = 2
3x + 4y = 3 + 4 = 7
(3)(4) + xy = (3)(4) + (1 * 2) = 12 + 2 = 14
So, the expressions are not the same and Alexander is incorrect.
all have to do is divide the fraction to make it into a decimal ,
6/8= 0.75

The activity type would be the input and the cost would be the output. Because there are two different costs for the same activity, this would not be a function.

Hope this helps! :)
First make the fraction over 100
21/50(2/2) = 42/100
42/100 = 0.42
0.42 is your answer
hope this helps
