By using subtraction, Brenda needs an additional amount of $ 182.75 for the school trip.
<h3>How much money does Brenda need to save for her school trip?</h3>
In this question we notice that Brenda is aware of how much money she needs to make her school trip and besides we find a table with all the money saved during a 4-month period. Lastly, we must determine if the amount of money saved by Brenda is sufficient or not.
The money needed for the school trip is:
y = $ 197 + $ 230 + $ 85
y = $ 512
And the money saved by Brenda is:
x = $ 67 + $ 30.50 + $ 160 + $ 71.75
x = $ 329.25
Then, the additional money needed for Brenda is found by subtacting the second result from the first result:
z = y - x
z = $ 512 - $ 329.25
z = $ 182.75
Brenda needs an additional amount of $ 182.75 for the school trip.

Answer:
A
Step-by-step explanation:
An ordered pair is a solution if when substituted it makes the equation true. If when you substitute, it does not make the equation true then it is not a solution.
y = -5x - 4
Test:
-52 = -5(10) - 4
-52 = -54 FALSE
-39 = -5(7) - 4
-39 = -39 TRUE
31 = -5(-7) - 4
31 = 31 TRUE
-44 = -5(8) - 4
-44 = -44 TRUE
