Set up a system of equations.
0.10d + 0.25q = 39.25
d + q = 250
Where 'd' represents the number of dimes, and 'q' represents the number of quarters.
d + q = 250
Subtract 'q' to both sides:
d = -q + 250
Plug in '-q + 250' for 'd' in the 1st equation:
0.10(-q + 250) + 0.25q = 39.25
Distribute 0.10:
-0.10q + 25 + 0.25q = 39.25
Combine like terms:
0.15q + 25 = 39.25
Subtract 25 to both sides:
0.15q = 14.25
Divide 0.15 to both sides:
q = 95
Now plug this into any of the two equations to find 'd':
d + q = 250
d + 95 = 250
Subtract 95 to both sides:
d = 155
So there are 95 quarters and 155 dimes.

Step-by-step explanation:
Answer:
5
Step-by-step explanation:
Given that:
Total maximum amount that the owner wishes to spend = $20000
Average price of each car = $4000
To find:
How many cars that the owner can expect to buy?
Solution:
Total number of cars that the owner can expect to buy can be found by dividing the total money available with the owner with the average price of each car.
i.e.
We have the following values as given in the question statement:
Total money available = $20000
Average price of car = $4000
Therefore, the answer is:
The owner can expect to buy 5 number of cars.
Answer:
the average story is 10 feet and the car is below ground so it would be negative. i assume the answer would be -20 feet
Step-by-step explanation:
Answer:
$481.25
Step-by-step explanation:
The number of transactions is 175.
The fee per transaction is $2.75.
The total fees is calculated as:
Number of transactions × Fee per transaction
175 × $2.75
$481.25
