Algebraic equations are equations that contain unknown variables. Unknown variables in algebraic equations can be represented using alphabets.
The value of f(7-4) is 72. Option B is the correct option.
The function for the cost of renting a mountain bike for one or more days is given as: f(n)= 12+20n
where
n= number of days
f(n)= total cost in dollars.
The value of f(7-4) is calculated as;
f(7 - 4) = f(3)
This means n = 3
Hence, f(3) = 12 + 20 x 3
f(3) = 12 + 60
f(3) = 72
Therefore, the value of f(7-4) is 72. Option B is the correct option.
