Carlos is hoping to save at least $200 in the next four weeks. His mom gives him $30, and he earns money each Saturday morning at his grandmother’s store. Write an inequality for the amount of money Carlos will need to earn each Saturday morning, and describe the solutions. Assume Carlos will earn the same amount each Saturday morning
Let "x" represent the amount of money Carlos needs to earn each Saturday morning.
The inequality to represent Carlos's goal would be:
x * 4 + 30 ≥ 200
Simplifying the inequality:
4x + 30 ≥ 200
Subtracting 30 from both sides:
4x ≥ 170
Dividing both sides by 4:
x ≥ 42.5
Therefore, Carlos needs to earn at least $42.50 each Saturday morning to save at least $200 in the next four weeks.
