Question: Keiko sent 111 text messages last week. This week she sent 50 less than double what she sent last week. How many text messages did Keiko send last week and this week combined? Is final answer 283?
Answer: Last week = 111 texts
This week = (2 * 111) - 50 = <<(2*111)-50=172>>172 texts
111 + 172 = <<111+172=283>>283 texts
Keiko sent 283 texts last week and this week combined.
