A student is enrolled in a materials chemistry course where the homework is weighted $10\%,$ the midterm is weighted $30\%,$ and the final exam is weighted $60\%.$ The student scored $95\%$ on their homework, $80\%$ on their midterm, and $75\%$ on their final exam. Determine the expression used to calculate the final grade for the student in their materials chemistry course.

$95\%+80\%+75\%0\mathrm{.}10+0\mathrm{.}30+0\mathrm{.}60$

$0\mathrm{.}10(0\mathrm{.}95)+0\mathrm{.}30(0\mathrm{.}80)+0\mathrm{.}60(0\mathrm{.}75)$

$0\mathrm{.}10(90\%)+0\mathrm{.}30(70\%)+0\mathrm{.}60(40\%)$

$0\mathrm{.}10(95\%)+0\mathrm{.}30(80\%)+0\mathrm{.}60(75\%)$
