<em>If the line is a vertical line on a graph, then this means that the </em><em>x coordinate is 0</em><em> while the </em><em>y-intercept is un-identified.</em><em> Looking at the options and the formula, </em><em>x = 0 </em><em>is the most reasonable option because a </em><em>vertical line on a coordinate plane basically defines that the x coordinate is 0.</em>
Multiply $1.50 and 60%, which will give you 0.9. now multiply $1.50 and 0.9 and that'll give you$1.35. lastly, add $1.50 and $1.35 and that'll give you the answer which is $2.85.
