283136/1792 Is your CORRECT answer
Answer:
0.15 for each message
Step-by-step explanation:
The charge per message can be found by dividing the charge by the number of messages. Using the first line of the table, we get ...
charge per message = (total charge)/(number of messages) = $38.40/256
charge per message = $0.15
Alyssa is charged 0.15 for each text message.
_____
We can check other lines of the table to see if charges are really proportional:
$26.55/177 = $0.15
$31.35/209 = $0.15
Answer:
y = -13.75x + 340
120 owls in 2019
Step-by-step explanation:
To find the population in a future year, use the formula y=mx+b since it changes linearly.
So over 4 years the owl population changed from 285-340=-55. Divide by 4 and this is a yearly change of -13.75. This is m.
The y-intercept is the starting point known as b in the equation. Here it is 340.
So the equation is y=-13.75x+340.
In 2019, t=16 so y=-13.75(16)+340 = 120.
