Answer:
A 28 and 45
Step-by-step explanation:
So keep in mind that columns must add up to the total numbers, and rows must add up to their total numbers.
We know that what goes in the box canoeing + swimming is
x + 43 = 71.
It needs to add up to 71!
x = 71 - 43 = 28
We know that what goes in the box no swimming + no canoeing is
34 + y = 79
It needs to add up to 79.
y = 19 - 34 = 45
So the answer is A. 28 and 45.
Now, I did this with the columns, but you could easily do this with the rows and get the same result!
