<human>:  Camila has only gone hiking 7 times in her life. Amanda has gone on 8 times as many hikes as Camila, and Steven has gone on 15 more hikes than Amanda. If Camila wants to say that she has hiked as many times as Steven and plans to go on 4 hikes a week, how many weeks would it take Camila to achieve her goal?
<bot>: How many hikes has Amanda gone on? ** Amanda has gone on 7 hikes x 8 = <<7*8=56>>56 hikes.
How many hikes has Steven gone on? ** Steven has gone on 56 hikes + 15 hikes = <<56+15=71>>71 hikes.
How many hikes does Camila need to go on? ** Camila needs to go on another 71 hikes - 7 hikes = <<71-7=64>>64 hikes.
How many weeks will it take Camila to achieve her goal? ** Camila will achieve her goal in 64 hikes / 4 hikes/week = <<64/4=16>>16 weeks.
