The base cost of a computer is $650.00. The price increases as the memory for the computer increases, at $48.00 per gigabyte. If the total cost of a computer is C dollars, which equation would best represent its relation with the number of additional gigabytes, g? A. C = 650 + 48g
B. C + 48g = 650
C. C = 650 – 48g
D. 48g = C + 650

It would be

Step-by-step explanation:

The option d

A simple equation you could use to find the score James got on his first test would be x+18=86 where x is the score he received on the first test.

x+18=86
   -18-18
x=68

With this in mind, using the equation we created, we know that James received 68 points on his first test.
