Answer:
(y-5) ÷ 2
Step-by-step explanation:
392 boots. If you divide everything into "sets" of an unknown amount, there are 5 more "sets" of boots than sandals, also known as the 245 boots. So if you divide 245 by 5, you'll get the number of items in a "set". Then just multiply by 8 from the 8:3 ratio. If you check it, it will come out to 392 boots to 147 sandals, which I think is ridiculous since sandals are supposed to come in pairs so you should never have a odd number. But anyway, 392 - 147 = 245
If 4·10= 40 then 4·-10 would equal -40 bc a positive times a negative equals a negative.
Hope this helped!!
