Answer : Yes, regular and sale prices represent a proportional relationship.
Step-by-step explanation :
We have to determine the ratio of regular and sale prices of shirt, jeans and boots .
A shirt was originally $9.50 and now is $7.60.
A pair of jeans were $25.00, and now they are priced $20.00.
A pair of boots were $55.00, and they are on sale for $44.00.
From this we conclude that, all the items are in same ratio that means the regular and sale prices represent a proportional relationship.
Hence, yes, regular and sale prices represent a proportional relationship.

From the given points that are (3,1),(9,3),(27,9), we can say that x is three times of y. That is
x= 3y
And we need to solve for y. For that, we need to get rid of 3 from the right side by dividing both sides by 3 . And on doing so , we will get
or
Answer: a) Number of nickels, dimes, and quarters are 80, 120, 300 respectively.
b) The coins are worth of 91 dollars i.e. $91 in the piggy bank.
Explanation:
Since we have given that
For every 2 nickels there are 3 dimes ,
So, their ratio will be 2:3
and for every 2 dimes there are 5 quarters.\,
So, their ratio will be 2:5
Now, we'll first find the ratio of nickles to dimes to quarters i.e.
Nickle Dimes Quarters
2 3
2 5
So, it becomes ,
Nickle : Dimes : Quarters
2×2 : 3×2 : 3×5
4 : 6 : 15
Now, let the number of nickle be 4x
Let the number of dimes be 6x
Let the number of quarters be 15x
According to question,
So, number of nickels is given by
Number of dimes is given by
Number of quarters is given by
As we know that
So, According to our question, we get
Hence,
a) Number of nickels, dimes, and quarters are 80, 120, 300 respectively.
b) the coins are worth of 91 dollars i.e. $91 in the piggy bank.
