The sales tax is 2.88 because 6% of 48 is 2.88 so the original price before tax was applied was 45.12
Y=-5(x+1) is proportional you can simply find this out by going to desmos and it’ll allow you to input an equation and you can see how it aligns
so from accidental deaths we have
30 from falls
47 from fires
200 from drowning
1950 car accidents
so the total of those is 30+47+200+1950, or 2227.
the ones that weren't car accidents will be 2227 - 1950, or 277.
if we take 2227 to be the 100%, how much is 277 off of it in percentage?
