Before getting to work, Jess has a few errands to run. Jess has to walk 11 blocks to the store and 6 blocks to the gallery, before walking the final 8 blocks to arrive at work. If Jess has already walked 5 blocks, how many more blocks must she walk before arriving at work?
Jess needs to walk 11 blocks + 6 blocks + 8 blocks = <<11+6+8=25>>25 blocks total.
Jess needs to go 25 blocks – 5 = <<25-5=20>>20 blocks to get to work.
