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?
Amanda has gone on 7 hikes x 8 = <<7*8=56>>56 hikes.
Steven has gone on 56 hikes + 15 hikes = <<56+15=71>>71 hikes.
Camila needs to go on another 71 hikes - 7 hikes = <<71-7=64>>64 hikes.
Camila will achieve her goal in 64 hikes / 4 hikes/week = <<64/4=16>>16 weeks.
