Our math team had m students last year, but this year it has already n students! By what percent did the number of students grow?

(n-m)/m * 100%

Step-by-step explanation:

The original amount is m

The new amount is n

Take the new amount and subtract the original amount

(n-m)

Divide by the original amount

(n-m)/m

Multiply by 100 %

(n-m)/m * 100%

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
