Sandra saves 8% of her salary for retirement. This year her salary was $2,000 more than in the previous
Tanya [424]

Answer:

\$40000

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:

\$3360=8\%x\\

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

$3360=\frac{8}{100}x

Multiply 100 to both sides:

336000=8x

Divide both sides by 8

x=42000

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:

42000-2000=40000

Elina [12.6K]

Answer:

C) 63.9 square units

Step-by-step explanation:

From the above diagram, we can see that the triangle has 2 sides and and angle

The formula for the area of a triangle that has 2 sides and an angle = 1/2absinθ

θ = 70°

a = DE = 8 units

b = EF = 17 units

Area of ΔDEF = 1/2 × 8 × 17 × sin 70°

Area of ΔDEF = 63.9 square units.
