Answer:
The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.

Interpreting graphs of proportional relationships
Answer:
after 4 months $8352.96
AFTER 13 MONTH $7426.507
AFTER 23 MONTH A = 7675.69
Step-by-step explanation:
Given data:
P = $9388.81
Compound interest cab be determined as
A = P( 1+ r/n)^(nt)
after 4 months

A = 9513.58
But he has to pay $1160.62 after 4 month so remaining amount is
P = 9513.58 - 1160.62 = $8352.96
AFTER 13 MONTH, so total time is 9 month

A = 8604.79
But he has to pay $1178.29 after 13 month so remaining amount is
P = 8604.79 - 1178.28 = $7426.507
AFTER 23 MONTH so total time is 10 month

A = 7675.69
