Elsie would like to take snowboarding lessons at powder mountain. she has saved $550 for lessons and a junior season pass that costs $315. she wants to take semi-private lessons that cost $45. how many semi- private lessons can she take?

So, she has 550 dollars saved. If the junior season pass costs 315, you subtract that from 550. You should then have 235 dollars. Next, you divide 235 by 45 dollars per lesson, and you should get 5.22. You can't buy half a lesson, so she only has enough for 5 lessons. 

Gotta be d the music of previous eras
