Answer
$s(5)=22$
$s(10)=38$
Work Step by Step
The question is basically asking if $s(t)=3.2t+6$, then what is $s(5)$ and $s(10)$?
First lets review how to solve questions like these. If you want to find $s(1)$, you have to find $3.2(1)+6$, because you are basically plugging in $1$ into the expression $3.2t+6$ as $t$.
$s(5)$: Do the same thing as I mentioned before, by plugging in $5$ as $t$ in $3.2t+6$.
$3.2t+6$ (The original expression)
$3.2(5)+6$ (Substitution)
$16+6$ (Multiply)
$22$ (Add)
$s(10)$: Same principle.
$3.2t+6$ (The original expression)
$3.2(10)+6$ (Substitution)
$32+6$ (Multiply)
$38$ (Add)
