Sometimes, more than one expression can describe the same situation.

Suppose you have a pocketful of change. You have some pennies ( [tex]p[/tex] ) and some quarters ( [tex]q[/tex] ). One expression could be used to describe the total number of coins in your pocket:
[tex]\[ p + q \][/tex]

A second expression could be used to describe the amount of money (in dollars) in your pocket:
[tex]\[ 0.01p + 0.25q \][/tex]

Notice that each expression describes a different characteristic of the change in your pocket.

Evaluate each expression for the situation where you have 6 quarters and 7 pennies in your pocket.

Type the correct answer in each box. Use numerals instead of words. For the amount of money, do not enter a dollar symbol.

The number of coins is [tex] p + q = \square [/tex].

The amount of money is [tex] 0.01p + 0.25q = \square [/tex].


Sagot :

To evaluate the expressions for the given situation where you have 7 pennies (p = 7) and 6 quarters (q = 6), we can proceed as follows:

1. Total Number of Coins:
The expression to calculate the total number of coins is [tex]\( p + q \)[/tex].

Substituting the given values:
[tex]\[ p + q = 7 + 6 = 13 \][/tex]

Thus, the total number of coins is 13.

2. Amount of Money in Dollars:
The expression to calculate the total amount of money is [tex]\( 0.01p + 0.25q \)[/tex].

Substituting the given values:
[tex]\[ 0.01p + 0.25q = 0.01 \times 7 + 0.25 \times 6 \][/tex]

Breaking this down:
[tex]\[ 0.01 \times 7 = 0.07 \quad \text{(value of pennies)} \][/tex]
[tex]\[ 0.25 \times 6 = 1.50 \quad \text{(value of quarters)} \][/tex]

Adding these amounts together:
[tex]\[ 0.07 + 1.50 = 1.57 \][/tex]

Thus, the total amount of money is 1.57 dollars.

Now, filling in the boxes with the evaluated expressions:
- The number of coins is [tex]\( p + q = 13 \)[/tex].
- The amount of money is [tex]\( 0.01p + 0.25q = 1.57 \)[/tex].

So, the final answers are:
- The number of coins is [tex]\( 13 \)[/tex].
- The amount of money is [tex]\( 1.57 \)[/tex].
