9/8=12/p -----> divide by 12 on both side
9 1. 9
-- x -- = ---- = 8
8 12. 72
p=8
hope this helped:)
Translating "The tax is some percent of the phone's price" into an equation, we get:
42.42 = p · 499
If we divide both sides by 499, we get
0.085 ≈ p
We can check by finding 8.5% of 499:
0.085 · 499 = 42.415, which rounds to 42.42
So the tax rate was 8.5%.
Are you sure this is an actual thing... I'm just sayin ive never see this before
