Q. A cashier counts $15.75 in quarters and dimes at the end of a workday. Which of the following equations shows the relationship between the number of quarters, q, and dimes, d, that the cashier counted?Choose 1 answer:(A) q0.25+d0.10=15.75(B) 0.25q+0.10d=15.75(C) 0.35(q+d)=15.75(D) 0.25q+0.10d=15.75
Express Total Amount: We need to express the total amount of money in terms of the number of quarters q and dimes d. A quarter is worth $0.25 and a dime is worth $0.10. The total amount of money counted is $15.75. The equation should represent the total value of the quarters and dimes combined.
Write Equation Based: Let's write the equation based on the value of each coin. The value of q quarters is 0.25q dollars, and the value of d dimes is 0.10d dollars. The sum of these values should equal the total amount of money, which is $15.75.
Total Value Equation: The equation that represents the total value is: 0.25q+0.10d=15.75. This equation correctly represents the relationship between the number of quarters and dimes and the total amount of money.
