Step-by-step explanation: In order to find the number, we will need to set it up in an equation. In total, there are 460 students while 60% of them have pets. Lets set that up.
460(60%)
In order to correctly do this, we will need to transfer 60% into a decimal, which is .6. Now we will rewrite it.
460(.6)
This now can be represented by the number 276.
Since we know that 276 is 60% of 460, The total number of students that have pets will be 276.
To find the tip you have to change the percent into a fraction first. Since percent is out of a 100, 25% is 25/100 or 1/4. Multiplying 1/4 by 520 you get 130, which is how much the coach will tip.
