As a salesperson, you are paid $50 per day plus $3 per sale. This week you make $400. Define your variables then, write and solve an equation for the number of sales you made.

16.7 sales

Step-by-step explanation:

As a salesperson, you are paid $50 per day plus $3 per sale. This week you make $400. Define your variables then, write and solve an equation for the number of sales you made.

Let the number of sales be represented by x

As a salesperson, you are paid $50 per day plus $3 per sale. This week you make $400.

The number of days in a working week = 5

Hence:

Total Amount made(A) = $400

Hence

$50 × 7 + $3 × x = $400

350 + 3x = 400

3x = 400 - 350

3x = 50

3x = 50

x = 50/3

x = 16.7 sales

Therefore, the number of sales you made = 16.7 sales

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
