Jenny has been saving her babysitting money for a class field trip to washington, d. c. she wants to save $200.00 over three months. she saved $53.00 the first month and $67.00 the second month

To estimate, $53 is about $50 and $67 is about $70 so she currently has about $120. She needs about $80 (or more) to reach her goal of $200.

To calculate this answer, you simply add $53 to $70 and get $120. You can then subtract $120 from $200 to get $80. So in the third month, Jenny must get at least $80 more dollars to get to her goal of $200.
