a man got a 4000 dollar said which equated to an 11% raise. What was his salary before the raise?
i set it up .11(x) = 4000+x
i got roughly 36,000
it should say got a 4000 dollar raise which equated to 11% increase in his salary*****
so you are asking $4000 is 11% of what number
translate into math \[4000=.11\times x\]
"is" becomes = "of" becomes x and "what number" is our variable.
solve in one step via \[x=\frac{4000}{.11}\]
oh and of course i should add that 11% becomes .11 because we compute with numbers, not percents.
i get an original salary of $36,363.63
cool, thats what I got i actually had 4000-x = 1.11*x
so it equated to the same but by dumb luck :) thanks!
i mean 4000+x wow im struggling
well actually your equation was exactly the same i think. just more work to solve and rather convoluted for this basic problem
hahah yes I agree
subtract x, get \[.11x=4000\] etc
