Sandwich Shop--Christian is working at Subplace. His boss tells him there needs to be at least $50 in the register by the end of his shift. There was already $6 inside at the start of the day. If each sandwich at his shop costs $5.50, what is the minimum number of sandwiches he has to sell in order to have at least $50?
Write and solve an inequality. Symbols are here if you need to copy/paste: < > ≥ ≤
"To meet his goal, Christian would..."

Model--Read the text, then just write an inequality to model the situation. You do not have to solve.
Angel did extra chores over the holidays to save up money for computer parts. He has $120 saved up already. He can earn $20 per week by doing other work around the house.
If the processor he wants to buy (called the AMD 3700x) is $349, what is the minimum number of weeks he would have to work to pay for the computer part?

Just Solve--Practice solving the inequality given to you by using inverse operations (treat it like an equation and get the variable by itself).
What are three possible values of y?
4y-6\geq10
