Luis spent $9.50, in which:
Candy (y) = $1.25
Chips (x) = $0.50
$9.50 = 1.25y + 0.50x
Luis bought 10 snacks in all
10 = x + y
-----------------------------------------------------------------------------------------------------------------
You're answer:
x + y = 10
1.25y + 0.50x = 9.50

Answer:
A = 2:15
B = 5:32
C= 12:45
D = 6:42
Step-by-step explanation:
A function is a tool within mathematics that takes an input, performs a series of operations and then gives an output. The notation for a function takes the form: f(x) = algebraic expression. Here, f is the name of the function and x is the independent variable. Any algebraic expression can be on the right of the equals sign. None of the answers are particularly satisfactory in this case, but (d) is the closest: distance(time) = 800. The main problem being the independent variable is not on the right hand side of the equation.
