Create a real world equality problem, then solve:
Example Problem:
Ana sells at least 220 shirts:
Ana Sold 85 shirts in the first 3 weeks of the month:
How many shirts must Ana sell in the last week of the month?
Solution:
Let S = the number of shirts Ana sells in the last week of the month.
Total Number of Shirts for the month must be greater than 220:
We Write: 85 + S ≥ 220
We Solve the inequality by Subtracting 85 from both sides: S ≥ 135
Therefore, Ana must sell 135 or more shirts in the last week to go on the school trip.
Solve: 85 + s ≥ 220 ========> S ≥ 135
Let's solve your inequality step-by-step.
85 + s ≥ 220
Step 1: Simplify both sides of the inequality.
s + 85 ≥ 220
Step 2: Subtract 85 from both sides.
s + 85 − 85 ≥ 220 − 85
s ≥ 135
Answer:
s ≥ 135
Check Problem:
85 + s ≥ 220 ========> S ≥ 135
We see that =====> 85 + 135 = 220
If Ana sells 135, or more shirts, The total number of shirts she sells that month will be 220 or more ========> Answer Checked
Hope that helps!!!!!!!!!!! : )
