Step-by-step explanation:
Area of the Parallogram =bh
8√90=2✓5*h
12✓2=h
...................
Amount spent on the last call = $25 - $22.04 = $2.96 = 296 cents
Number of minutes used for last call = 296 / 8 = 37 minutes.
400, if you can buy 4 tickets for $6 you can buy 400 for $600
Both companies charge the same amount I am assuming you are asking which to go with?<span />
