Answer:
John attempted 500 passes this year.
Step-by-step explanation:
We know that John completed 350 passes which is 70% of all passes.
To know the total number of passes he did, we just need to use the rule of three. If 350 passes represents 70%, how many passes would represent 100%?
[tex]100\%\frac{350}{70\%}=500[/tex]
Therefore, John attempted 500 passes, from which he completed 350 that represents a 70%.
