If the scale factor is above one it’s enlargement because it’s making the shape bigger but if it’s less than one it’s a reduction because it’s reducing the size of the shape so a scale factor of 3.5 is enlargement

Huhhhhhhhhh whaatttt ?!?!
The total tickets to be purchased to guarantee the win = 504 tickets
Step-by-step explanation:
Step 1 :
Number of entries in the trifecta race = 9
The win is to select the first finisher, second finisher and third finisher in their proper order.
We need to find the number of tickets to be purchased to guarantee the win
Step 2 :
Number of ways to select the first finisher = 9
Number of ways to select the second finisher = 8 [the first is selected and fixed. So the number of available finishes is reduced by 1]
Number of ways to select the third finisher = 7
Hence the total tickets to be purchased to guarantee the win = 9 × 8 × 7 = 504
Step 3 :
Answer :
The total tickets to be purchased to guarantee the win = 504 tickets
The answer would be 10 times because if you divide 220÷22 would equal 10.
