Answer:
$32000
Step-by-step explanation:
Let last years salary was $x
Therefore,
x + 3% of x = $32960
x + 0.03x = $32960
1.03x=$32960
x = 32960/1.03
x = $32,000
So, last year's salary was $32000.
Normally it is x ininput and f(x)=y
solve for y and replace y with f(x)
minus 5x from both sides
2y=10-5x
divide both sides by 2
y=5-2.5x
f(x)=5-2.5x
