Answer:
To stay within budget, she must use 4.4 gigabytes.
Step-by-step explanation:
Giving the following information:
Fixed cost= $57.50 per month
Variable cost= $4 per gigabyte.
She wants to keep her bill at $75.10 per month.
<u>First, we need to establish the total cost formula:</u>
Total cost= 57.5 + 4*x
x= number of gigabytes
<u>Now, we isolate x:</u>
75.1= 57.5 + 4x
17.6/4= x
4.4= x
To stay within budget, she must use 4.4 gigabytes.
1. We first simplify both sides of the equation, factoring the parentheses and adding like numbers:

Then, we move all the Xs to one side and all the numbers to the other by subtracting 3x from both sides and adding 3 to both sides:

We get x = 4.
2. First, we simplify:

Then, we try to move the Xs to one side, but we get 13x - 13x, which equals 0x. This problem is impossible, as it states 45 = 10.
