63=21% of all
percent is parts out of 100
63=21/100 of all
times both sides by 100/21
6300/21=all
300=all
all-wednesday=thu+fri
300-63=thu+fri
137=thu+fri

For this case we have the following variable:
m = Santana's total marbles
We must write an expression as a function of m to model the problem.
"Santana wants to give one-thenths of all his marbles plus eight to his brother"
The function is:
f (m) = (1/10) m + 8
Answer:
An expression that Santana can use is:
f (m) = (1/10) m + 8
Wouldn’t it just be (0,0) ?
