Solve as if you were solving an equation. Write a circle on the hash mark representing the number #3.0# on the number line. Shade the entire number line to the left of the number #3.0#.

Explanation:

#P-1.5<1.5#

Add #1.5# to both sides of the inequality.

#P<1.5+1.5##=#

#P<3.0#

On a number line, circle the hash mark representing #3.0#. Then shade the line to the left of #3.0# all the way to the arrow. The interval notation for this inequality is #(-oo,3)#.
