Y=18 is the correct answer
Answer:
-$5.27 per day
Step-by-step explanation:
1st. $300
6th. $273.65
19th. $205.14
25th. $173.52
28th. $157.71
Lets use the one that has the least amount of days separated to make it easier
28th and 25th
157.71 - 173.52 = -15.81
count how many days are separated (3)
then divide that to what the amount is
-15.81 / 3 = -$5.27 per day
Answer:
The answer would be (1.23, 4.39)
Step-by-step explanation:
Because they are both equal to y, we can set the equations equal to each other and then solve.
4.9x - 1.64 = -0.25x + 4.7
5.15x - 1.64 = 4.7
5.15x = 6.34
x = 1.23
Now that we have the value for x, we can plug into either equation and find y.
y = -0.25x + 4.7
y = -0.25(1.23) + 4.7
y = -.31 + 4.7
y = 4.39
