Answer:

2,000
$45,000

Step-by-step explanation:

Where x represents the previous year's salary, its amount this year is said to be ...

x + 2000

The equation is trying to reflect the fact that 7% of that is $3,290. The missing number is 2000:

0.07(x +2000) = 3290

Solving for x, we find ...

x = (3290/0.07) -2000 = 45000

Sandra's salary the previous year was $45,000.
