To solve this problem, we start by determining how much more money Kris needs to earn to reach her goal of at least $1,625 by the end of summer.
-
Calculate how much more Kris needs: \[ 1625 - 190 = 1435 \] So, Kris needs to earn at least $1,435 more.
-
Let \( x \) be the amount of money Kris needs to earn each weekend. Since she wants to earn this amount over 8 weekends, we can write the inequality: \[ 8x \geq 1435 \]
-
To find \( x \), divide both sides of the inequality by 8: \[ x \geq \frac{1435}{8} \] \[ x \geq 179.375 \]
-
Rounding this to two decimal places, we get: \[ x \geq 179.38 \]
Thus, Kris needs to earn at least $179.38 each weekend to meet her goal.
Now, we'll consider the response options:
- Kris needs to earn $13.13 each hour to meet her goal. (This choice is incorrect as the earning calculation is per weekend, not per hour.)
- Kris needs to earn at least $179.38 each weekend to meet her goal. (This choice is correct.)
- Kris needs to earn $105 more to meet her goal. (This choice is incorrect as she needs to earn $1435 more.)
- Kris needs $179.38 more to meet her goal. (This choice is incorrect, she needs to earn that amount each weekend, not an additional amount.)
The best interpretation of the solution is: Kris needs to earn at least $179.38 each weekend to meet her goal.
