To find out how much money Kris needs to earn each weekend, we can set up an inequality based on her current amount and her goal.
Kris currently has $190 and wants at least $1,625 by the end of the summer. She plans to earn money over the course of 8 weekends. Let's denote the amount Kris needs to earn each weekend as \( x \).
The total amount of money Kris will have at the end of the summer can be represented as: \[ 190 + 8x \]
To meet her goal of at least $1,625, we can write the inequality: \[ 190 + 8x \geq 1,625 \]
Now, we can solve for \( x \):
-
Subtract 190 from both sides: \[ 8x \geq 1,625 - 190 \] \[ 8x \geq 1,435 \]
-
Divide both sides by 8: \[ x \geq \frac{1,435}{8} \] \[ x \geq 179.375 \]
Therefore, Kris needs to earn at least $179.38 (when rounded to two decimal places) each weekend to meet her goal.
The correct interpretation in the context of the problem is: Kris needs to earn at least $179.38 each weekend to meet her goal.
