<u>Answer:</u>
Nadia's total earnings in month is $3196.1
<u>Explanation:
</u>
Given salary of Nadia is $3,300 per month including a 3.25% commission
The salary consists of fixed salary and commission

Answer:
The equation, y=3 x,
Step-by-step explanation:
y=Distance traveled
x =Total time
Also, in terms of straight line
Slope =3= uniform Velocity
Point (3,9) and (5,15) represents Distance traveled in 3 (unit of time) =9 unit, and 15 unit=Distance traveled in 5 (Unit of time).
→Alonso is moving with uniform speed=3 (unit of time), as velocity remains constant in the entire process.
