Targeted TEKS
A.2(H) Write linear inequalities in two variables
given a table of values, a graph, and a verbal
description.
A.5(B) Solve linear inequalities in one variable,
including those for which the application of the
distributive property is necessary and for which
variables are included on both sides.
Mathematical Processes
A.1(E), A.1(F)
Solve by Adding

than four times that number plus 8.
Use an Inequality to Solve a Problem
ENTERTAINMENT Panya wants to buy season
passes to two theme parks. If one season pass
costs $54.99 and Panya has $100 to spend on both
passes, the second season pass must cost no
more than what amount? Write and solve an
inequality that represents this situation.
BREAKFAST Jeremiah is taking two of his friends
out for pancakes. If he spends $17.55 on their
meals and has $26 to spend in total, Jeremiah’s
pancakes must cost no more than what amount?
Write and solve an inequality that represents this
situation.
