Suppose you have a pocketful of change. You have some pennies (p) and some quarters (q). One expression could be used to describe the total number of coins in your pocket: p + q. A second expression could be used to describe the amount of money (in dollars) in your pocket: 0.01p + 0.25q. 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.

13

1.57

Step-by-step explanation:

So we have two equations regarding the number of quarters q and the number of pennies p:

Which represents the total amount of coins and

Which represents the total amount of money in dollars.

So we are asked to evaluation each expression for the situation in which we have 6 quarters and 7 pennies. Thus, plug 6 in for q and 7 in for p:

This tells us that we have 16 coins in total.

This tells us that we have a total amount of $1.57.

Step-by-step explanation:

Pennies ⇒

First expression describes the total number of coins in the pocket ⇒

Second expression describes the amount of money in dollars in the pocket ⇒
