Mave currently has a hundred and thirty dollars and plans to earn more money each of the eight weekends this summer. She wants at least one thousand two hundred and fifty dollars by the end of summer. How much does she need to earn each weekend? Assume she earns the same amount each week and. Solve her problem and then grab the solution on the number line.
Mave currently has $130 and wants to have at least $1,250 by the end of summer. This means she needs to earn an additional $1,250 - $130 = $<<1250-130=1120>>1,120.
Since she has 8 weekends to earn this money, she needs to earn $1,120 / 8 = $<<1120/8=140>>140 each weekend. Answer: \boxed{140}.
