Answer:
a subset of integers
Step-by-step explanation:
You have to look at the definition of the variable and the meaning of the function value in order to determine suitable domain values.
Here, the variable is defined as a number of dimes. It must be a non-negative integer, a subset of the integers. (We cannot count fractional dimes or negative dimes.)
___
Since the variable represents "a handful of dimes", there must be an upper limit on its value. We expect that it will be something less than 1000 (20 rolls of dimes), but it might be slightly more.

5.5x+180=455
5.5x=275
The answer is X=50
Let the original cost of laptop=x
Savings=20% = 20/100
Saved amount = $140
Original cost = saved amount * 1/savings
x = 140* 100/20
x = $7000
Answer:
The expression which represents the quantity of tomatoes and red peppers to buy is $ 2.50 × T + $ 4 × R = $ 20
Step-by-step explanation:
Given as :
The total amount spend for soup = $ 20
The cost of Tomatoes = $ 2.50 per pound
The cost of Red peppers = $ 4 per pound
Let the quantity of tomatoes to be bought = T pound
The quantity of red peppers to be bought = R pound
So, According to question
$ 2.50 × T + $ 4 × R = $ 20
I.e The expression which represents the quantity of tomatoes and red peppers to buy is $ 2.50 × T + $ 4 × R = $ 20 . Answer
