Answer:
C is the dependent variable and r is independent
Step-by-step explanation:
Adriana can ride the bus any number of times she wants. No one is stopping her from doing that so 'r' becomes an independent quantity.
Whereas, the total cost for the bus rides depends on the number of times Adriana rides the bus and the relation is given as, C=1.25r
This is because it costs $1.25 each time she rides the bus in one direction
Answer: 45
Step-by-step explanation: 21 x 3 = 63, because 3x3 is 9. 9 tickets with a $2 discount would mean you take off $18, so I believe the answer would be 63-18=45.
Answer:
Alex will pay $3,662
Step-by-step explanation:
To find the total cost, we can make an equation modeling y=mx+b, with y being the total cost, m being the monthly charges, x being the amount of time it takes, and b being the 10% down payment.
After plugging in the numbers to the equation, we get y=276(12)+350.
Now all that is left is to solve the equation as follows:
y=3,312+350
y=3,662
A quics way to do this :-
9C5 = 9*8*7*6*5 3 * 7 * 6 = 126
------------- =
5*4*3*2*1
