To solve this problem, we need to subtract Maeve's current amount of money from the desired amount of money she wants to have at the end of the summer.
$1,250 - $130 = $1,120
So, Maeve needs to earn $1,120 in total over the 8 weekends.
To find out how much she needs to earn each weekend, we divide the total amount by the number of weekends.
$1,120 ÷ 8 = $140
Therefore, Maeve needs to earn $140 each weekend.
On the number line, this can be shown by plotting a closed point at $140 and extending an arrow to the right to represent the possibility of earning more money beyond $140.
Answer: The solution is represented by the second image, which shows a number line labeled "Maeve's Earnings This Summer" ranging from 0 to 180 in 20 unit increments, with a closed point plotted at 140 and an arrow extending to the right beyond 180.
