Answer:
(c) Equation which can be used to find r, the cost in dollars to park s nights is r = 24.99 s
Step-by-step explanation:
Here, the parking cost of 1 night at the airport = $24.99
Now, here the total number of nights the car is parked at airport = s
R = The total cost of parking s nights
Now, The cost for parking s nights = s x ( Cost of parking 1 night)
= s x ($24.99) = 24.99 s
Also the cost for parking s nights = r
⇒ r = 24.99 s
Hence, equation which can be used to find r, the cost in dollars to park s nights is r = 24.99 s

Answer:
6 Nickels
42 Dimes
Step-by-step explanation:
There are 48 coins in total (nickels and dimes). Let the number of nickels be "n" and the number of dimes be "d". So we can write:
n + d = 48
or
n = 48 - d
In dollars, we know nickels are worth 0.05 and dimes are worth 0.10. In total there is $4.50, so we can write:
0.05n + 0.10d = 4.50
Now replacing first equation [n = 48 - d] into 2nd, we get and equation in "d" and solve for d first:
So, there are 42 dimes.
We know from before, n = 48 - d, so
n = 48 - 42 = 6
There are 6 nickels
