3 0

The first aim of the numerations and numbers in general is to be able to compare things and to know what is bigger and what is smaller.
We compare numbers every day in our daily routine. For example: on the market, we compare the price of the products (the price of the apples for example refers to a real-world number). Or we compare the temperature during the day and during the night, which is also a real-world number.

Suppose you have just enough money, in coins, to pay for a gallon of milk priced at $2.40. You have 12 coins, all quarters and d

wel

The answer is
q + d = 12
0.25q + 0.10d = 2.40

q - the number of quarters
d - the number of dimes

You have 12 <span>coins, all quarters and dimes:
q + d = 12

The value of 1 quarter is $0.25.
The value of 1 dime is $0.10.
Therefore, if you want to pay </span>$2.40 you will have q quarters of value $0.25(0.25q) and d dimes of value $0.10d (0.10d).
The second equation is:
0.25q + 0.10d = 2.40
