the cost of living last year went up 6%. fortunately, alice swanson got a 6% raise in her salary from last year. this year she is earning $31,810. how much did she make last year? $ (round to the nearest hundredth.)
Answer
Explanation:
Step1: Let last - year salary be $x$.
The salary this year is the last - year salary plus a 6% raise. So, the equation is $x+0.06x = 31810$.
Step2: Combine like terms.
$1.06x=31810$.
Step3: Solve for $x$.
$x=\frac{31810}{1.06}$.
Step4: Calculate the value of $x$.
$x = 30009.43396$.
Step5: Round to the nearest hundredth.
$x\approx30009.43$.
Answer:
$30009.43$
