An administrative assistant at a community college is auditing a mailing expense for a department. The total spent was {}14.74 for a combination of 49-cent stamps and 20-cent stamps. The record indicates that the number of 49-cent stamps purchased was 'four less than three times the number of 20-cent stamps.' If $x$ represents the number of 20-cent stamps, which algebraic expression correctly represents the number of 49-cent stamps?

In the process of solving the stamp mixture problem where Kailee spent {}14.74 on 49-cent and 20-cent stamps, if $x$ represents the number of 20-cent stamps, the total value equation is correctly represented as ${}0.49(3x - 4) + 0.20x = 14.74$.

An office manager is reconciling a receipt for {}14.74 spent on two types of postage: 20-cent stamps and 49-cent stamps. The records indicate that the number of 49-cent stamps purchased was four less than three times the number of 20-cent stamps. To model this situation algebraically using the total-value method, match each description with its correct algebraic representation.

An office administrator is reconciling a postage expense of {}14.74 for a bulk mailing project. The shipment used both 49-cent and 20-cent stamps, and the records show that the number of 49-cent stamps was four less than three times the number of 20-cent stamps. Arrange the steps of the problem-solving strategy in the correct order to determine the quantity of each stamp type.

An administrative assistant at a local firm is reconciling a postage receipt for a total of {}14.74. The purchase included a combination of 49-cent stamps and 20-cent stamps. When using the total-value model equation ${}0.49(3x - 4) + 0.20x = 14.74$ to verify the quantities, the expression $(3x - 4)$ represents the ____ of 49-cent stamps purchased.
