Answer:
$88
Step-by-step explanation:
One way to calculate the percent of a number is to multiply the percent by the total value:
60% is equivalent to 0.6
Multiply 0.6 x 220
0.6 x 220 = 132
Since it is 60% OFF, you subtract 132 from 220
220 - 132 = 88

Answer:
Both sports = 15
Step-by-step explanation:
Remark
What an interesting question. At first I didn't think it was possible. Then I saw the word only. That made all the difference in the world.
Givens
Football only = 35
Volleyball only = 15
Ratio = 5/3
Equation
Let the number of students who play both = x
Volleyball / Football = (x + 15) /(x + 35) = 3/5
Solution
(x + 15) / (x + 35) = 3/5 Cross multiply
5*(x + 15) = 3(x + 35) Remove the brackets
5x + 75 = 3x + 105 Subtract 3x from both sides
<u>3x 3x</u>
2x + 75 = 105 Subtract 75 from both sides
<u> - 75 -75 </u>
2x = 30 Divide by 2
2x/2 = 30/2
x = 15
15 people play both sports.
