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? Think carefully first, then make a decision:
Last week = 111 texts. This week = (2 * 111) - 50 = 172 texts. 111 + 172 = 283 texts. Keiko sent 283 texts last week and this week combined. So, the answer is 283.
