8.99$/1 gallon
To write the cost as a unit rate (cost per gallon), we need to determine how much the paint would cost if we were buying exactly one gallon. Given the cost of $17.99 is for a half-gallon, we simply need to double that amount to find the cost for a full gallon:
$17.99 (for 1/2 gallon) * 2 = $35.98 for 1 gallon
So the correct unit rate is:
$35.98/1 gallon
