Given that Blake earns $35,351 in a year.
Let the donation amount be D.
Given that the donation is 27.9% of the total amount,
[tex]D=27.9\text{ percent of }35,351[/tex]Simplify the expression as,
[tex]\begin{gathered} D=\frac{27.9}{100}\cdot35,351 \\ D=0.279\cdot35,351 \\ D=9862.929 \end{gathered}[/tex]Thus, Blake should give $9862.929 to his local church.
