$s(5)=22$ $s(10)=38$

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)
