PLZ HELP ASAP THANKS IN ADVANCED!! :)

Answer 1

Every bottle costs $1.50

x = Number of bottles sold

x(1.50) = x times 1.50

Answer 2

$\underline{\ \ x\ \ |\ \ y}\\\underline{\ \ 0\ \ |\ \ 0}\\\underline{\ \ 1\ \ |\ 1.50}\\\underline{\ \ 2\ \ |\ 2\cdot1.5=3}\\\underline{\ \ 3\ |\ 3\cdot1.5=4.5}\\\underline{\ \ 4\ |\ 4\cdot1.5=6}\\\\\boxed{y=1.5x}$
