3 is the answer .... 109456+3 =109459
7*15637=109459
$35.00 x .20 = $7
So the discount would be $7 off of $35, for a final sale price of $28
Independent quantity (x) is number of races won
dependent quantity f(x)...or y is total virtual money
the function is : f(x) = 500x + 5000 or y = 500x + 5000
Hmm, it looks like it could be commutative property of multiplication.
The order of the expression is different.
4(2+3)=
4(5)=20
(2+3)4=
(5)4= 20
