A collection of 108 coins containing only quarters and nickels is worth $21. A table titled Coin Collection showing Number of Co
harina [27]

Answer:

q = 108-n

Step-by-step explanation:

Given: 108 coins containing only quarters and nickels

q = 108-n

since total number of coins is 108, and n= number of nickels

If you want to know how many of each kind of coin, read on:

First solve the number of quarters and nickels.

If all 108 coins are quarters, the value is 108*0.25 = $27

Since this value exceed the actual by 27-21 = $6,

we replace a number of quarters by nickels.

Each replacement will reduce the value by 25 - 5 = 20 cents = 0.2 dollars.

So it will take 6/0.2 = 30 replacements.

Therefore there are 108-35 = 78 quarters and 30 nickels.

What is the solution to the system of equations? y = A system of equations. Y equals StartFraction one-third EndFraction minus 1
lara31 [8.8K]

Answer:

(6,-8).

Step-by-step explanation:

We have been given a system of equations. We are asked to solve the given system.

y=\frac{1}{3}x-10...(1)

2x+y=4...(2)

From equation (2), we will get:

y=4-2x...(2)

Upon substituting this value in equation (1), we will get:

4-2x=\frac{1}{3}x-10

Upon multiply by 3 on both side, we will get:

3\cdot 4-3\cdot 2x=3\cdot \frac{1}{3}x-3\cdot 10

12-6x=x-30

12-6x-x=x-x-30

12-7x=-30

12-12-7x=-30-12

-7x=-42

\frac{-7x}{-7}=\frac{-42}{-7}

x=6

Upon substituting this in equation (2), we will get:

y=4-2(6)

y=4-12

y=-8

Therefore, the solution for our given system of equations is (6,-8).

PilotLPTM [1.2K]

Answer: The pre-tax price of the shirt for Macy will be $5.63

Step-by-step explanation:

Given:

Original price = 20

reduces selling price by 25% every month it's not sold.


First markdown month:

20 * (100%-25%) = 20 * 75% = 15


Second markdown month

15 * 75% = 11.25


Macy, employee gets a 50% discount off the current price.

11.25 * 50% = 5.625

11.25 - 5.625 = 5.625 or 5.63

hope it helps! :)
