Line Plots · Superchallenge problem

The numbers on the side of a bar graph of lunch votes have worn off, but the grid lines are evenly spaced and start at $0$. The pizza bar ends exactly halfway between the $7$th and $8$th grid lines, and the tacos bar ends exactly halfway between the $3$rd and $4$th grid lines. If each grid line had stood for $2$ more votes than it really does, the two bars together would have stood for $110$ votes. How many votes did pizza really get?
