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.(2 points)
4x+30≥200, where x is the amount Carlos earns each Saturday morning. Carlos must earn at least $____ each Saturday morning to have at least $200 in four weeks.
Carlos must earn at least $42 each Saturday morning to have at least $200 in four weeks.
no, 42 is wrong
Apologies for the mistake.
According to the given information, Carlos needs to save at least $200 in the next four weeks. He already has $30 from his mom. Let's say he earns x dollars each Saturday morning at his grandmother's store.
Since there are 4 weeks in total, Carlos will earn a total of 4x dollars in four weeks. Adding the $30 he already has, we can write the inequality as:
4x + 30 ≥ 200
The solution to this inequality is x ≥ 42.5.
Therefore, Carlos must earn at least $42.50 each Saturday morning to have at least $200 in four weeks.
