Answer:
The monthly growth rate is 2.1%
Step-by-step explanation:
To find the monthly growth rate, we have to consider what is inside the bracket
Mathematically, what we have in the bracket should be written as;
1 + r
Thus;
1 + r = 1.021
r = 1.021-1
r = 0.021
This is same as 2.1%
Divide everything by 4 getting:
7y=3x+21
then get all of the variables on one side by subtracting 3x:
7y-3x=21
