$color(crimson)(26.6$

$r = 12, s = 4$

$5 r - 8.35 s = (5*12) - (8.35 * 4)$

$=> 60 - 33.4 = 26.6$

$26.6$

$"substitute the given values for r and s into the expression"$

$(5xxcolor(red)(12))-(8.35xxcolor(blue)(4))$

$=60-33.4$

$=26.6$

$26.6$

We can just plug the values for the variables in our expression to get:

$5color(blue)((12))-8.35color(red)((4))$

$=>60-33.4$

$=26.6$

Hope this helps!
