Step-by-step explanation:
Let the weight 3 month ago be X.
20% more than x is:
1.2x
We now have the following equation:
1.2x = 36
x = 36/1.2
x = 30 pounds
Hope that helps! Have a good day :)
Ok so remember
x^n means x times itself n times
example
x^2=x times x
x^4=x times x times x times x
so
a^3
a=7
a^3=a times itself 3 times therefor
a^3=a times a times a
subsitute 7 for a
7^3=7 times 7 times 7
7^3=343
