Answer

Explanation:

Step1: Substitute A value

Given $A = 1.888x-3775$ and $A = 20.5$, we substitute $A$: $20.5=1.888x - 3775$.

Step2: Isolate the term with x

Add 3775 to both sides: $20.5 + 3775=1.888x$, so $3795.5 = 1.888x$.

Step3: Solve for x

Divide both sides by 1.888: $x=\frac{3795.5}{1.888}\approx2010.33$.

Step4: Round to whole - number

Rounding $2010.33$ to the nearest whole number gives $x = 2010$.

Answer:

2010
