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.
How much will he have to earn each saturday to have at least 200 on four weeks
Let x represent the amount of money Carlos will need to earn each Saturday morning.
The inequality to represent this situation is:
4x + 30 ≥ 200
The solutions to this inequality represent the possible amounts of money Carlos can earn each Saturday morning in order to have at least $200 saved in the next four weeks.
Hpw much will he have to earn each saturday? i didn't understand that part
To determine how much Carlos will have to earn each Saturday, we need to solve the inequality:
4x + 30 ≥ 200
First, we subtract 30 from both sides of the inequality to isolate the term with x:
4x ≥ 170
Then, we divide both sides by 4 to solve for x:
x ≥ 42.5
Therefore, Carlos will need to earn at least $42.50 each Saturday morning in order to have at least $200 saved in the next four weeks.
