Step One
Figure out the cost for 1 cartridge
Cost = 90
<u>Refund = 8 Subtract</u>
Net cost = 82
Step Two
Find the cost for 14
14 * 82 = 1148 <<<<<< Cost for 14
6/5. the other person was right so .
F(6) = -(6)^2 + 6(6) - 4
= -36 + 36 - 4
= -4

The average speed is 50 meters per second
<h3>How to determine the average speed?</h3>
The given parameters are:
Laps = 4
Time = 2 minutes
1 lap = 25 meters
Start by calculating the total distance
Distance = Laps * Meters
Distance = 4 * 25 meters
Distance = 100 meters
The average speed is then calculated as:
Speed = Distance/Time
This gives
Speed = 100 meters/2 minutes
Evaluate
Speed = 50 meters per second
Hence, the average speed is 50 meters per second

Answer:
x = 17
Step-by-step explanation:
We are going to call the missing angle in triangle EDC, "y"
x+y+100=4x+49+y
Eliminate the "y" on both sides
x+100=4x+49
move the x by subtracting the x on the left from the right
100= 3x +49
Move the numbers by subtracting 49 from 100
51 = 3x
Divide both sides by 3
17=x
