Your answer is C or $80
When averaging the costs of credit hours at public and private community colleges and four-year institutions, the median cost for a three-hour class in 2017 was $1,782. Conversely, each CLEP exam costs $85.
Answer:
The different variable in C is 21213316700.
Explanation:
Given value:
Total value = letters + underscore value
Total value = 52 + 1
Total value =53
choice for first character = 53 letters +10 digits
first character = 63
choice for remaining characters
So,
Variable number With one 1 character = 53
Variable number With 2 character = 53 × 63
Variable number With 3 character = 53 × 63²
Variable number With 4 character = 53 × 63³
.
.
.
Variable number With 7 character = 
Total difference variable = 53 + 53 × 63+ 53 × 63²+ 53 × 63³+....+ 
Total difference variable = 53(1 + 63 + 63²+ 63³+ .... +
)
Formula:

Total difference variable
