Sandra saves 8% of her salary for retirement. This year her salary was $2,000 more than in the previous year, and she saved $3,360. What was her salary in the previous year?

Step-by-step explanation:

Let's start by finding Sandra's salary this year.

We are given that she saved $3,360 or 8% of her total salary this year.

Let's represent her total salary this year as "x" and set up an equation:

Note that any percentage is equivalent to that number over 100.

Multiply 100 to both sides:

Divide both sides by 8

The question states "this year her salary was $2000 more than in the previous year".

This means that her salary in the previous year is equivalent to:

what the question so we can you out

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
