Which inequality is the Odd One Out?
Shante is buying movie tickets and gift cards
as prizes for her school fundraiser. She
needs at least five tickets and more than
two gift cards. A movie ticket cost $6 and a
gift card cost $10. The most she wants to
spend is $70. Write a system of linear
inequalities that represent the situation. Let
x be the number of tickets and y be the
number of gift cards to be purchased.
