Answer:
3500 tickets were sold on Saturday.
Explanation:
We know that percentages can be represented as decimals, for example, 75% can be represented as .75. For this example, we also know that 2000 were tickets sold on Friday. We are also told that the amount of tickets sold on Saturday is 175% of 2000. So, simply multiply 2000 by 1.75 and you will get the answer which is 3500.
