Question

"Just look at the graph," the player's agent said. "Phil's hits have doubled since last year. We are looking for a large raise and a long contract."
Look at the graph.
A bar graph titled Phil's hits has this year and last year on the x-axis, and number on the y-axis, from 100 to 200 in increments of 20. This year is 180, and last year is 120.
How can you redraw this graph so it appears that Phil's hits have quadrupled since last year.
a.
Use the same scale and make the top bar twice as thick as the bottom bar.
b.
Alter the scale so the top bar appears four times as long as the bottom bar.
c.
Both a and b.
d.
Neither a or b.
