a piggy bank contained $14.55 in quarters dimes and nickels if there were three more than twice as many dimes as nickels and three less than three times as many quarters as nickels how many of each kind of coin was in the piggy bank

Answers

Answer 1

Answer: Let x=number of nickels in the piggy bank
(2x+3)=number of dimes in the piggy bank
(3x-3)=number of quarters in the piggy bank

.05x+.10(2x+3)+.25(3x-3)=14.55
.05x+.20x+.30+.75x-.75=14.55

1.00x=14.55+.45
x=15
2x+3=33
3x-3=42

The number of nickles in the piggy bank would be 15.

The number of dimes in the piggy bank would be 33

The number of quarters in the piggy bank would be 42.

Hope I was able to help and that this was useful to you!!! :)

Answer 2

Answer: number of nickels in the piggy bank=15
number of dimes in the piggy bank=33
number of quarters in the piggy bank=42

If it costs $3 per hour to park in a parking lot, with a maximum cost of $12 Explain why the amount of time a car is parked is not a function of the parking cost

Answers

The cost of parking in a lot can be calculated as; Cost = cost rate x time. Let the time = t. When time, t = 1 hour, Cost = 3 x 1 = $3. When time, t = 2 hours, Cost = 3 x 2 = $6. When time, t = 3 hours, Cost = 3 x 3 = $9. When time, t = 4 hours, Cost = 3 x 4 = $12. When time, t = 5, Cost = 3 x 5 = $15 (notice, $15 has exceeded $12, but the maximum cost has to be $12). Thus, the cost of parking in a lot depends on the amount of time the car is parked and not vice versa. Therefore, the amount of time a car is parked is not a function of the parking cost because time is an independent variable and the cost of parking depends on the time the car is parked

Tickets to a concert are $35 each. In addition to the cost for the tickets ordered, there is a $15 processing charge per order.Write an expression that represents the total cost of an order of n number of tickets.

Answers

(35+15)n
Because each order is 35$ and it also charges 15$ for the processing charge order then u multiply it by n which is the amount of people

32% of what number is 56

Answers

let 32% of x = 56

32%*x = 56
32/100 *x = 56
x = 56*100/32
x = 5600/32 = 175

hence, 32% of 175 is 56.
