Let’s check out your problem:

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) 
(0.25 )/(q)+(0.10 )/(d)=15.75
(B) 
(q)/( 0.25)+(d)/( 0.10)=15.75
(c) 
0.35(q+d)=15.75
(D) 
0.25 q+0.10 d=15.75

Q. A cashier counts $15.75 \$ 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 q , and dimes, d d , that the cashier counted?\newlineChoose 11 answer:\newline(A) 0.25q+0.10d=15.75 \frac{0.25}{q}+\frac{0.10}{d}=15.75 \newline(B) q0.25+d0.10=15.75 \frac{q}{0.25}+\frac{d}{0.10}=15.75 \newline(C) 0.35(q+d)=15.75 0.35(q+d)=15.75 \newline(D) 0.25q+0.10d=15.75 0.25 q+0.10 d=15.75
  1. Express Total Amount: We need to express the total amount of money in terms of the number of quarters qq and dimes dd. A quarter is worth $0.25\$0.25 and a dime is worth $0.10\$0.10. The total amount of money counted is $15.75\$15.75. The equation should represent the total value of the quarters and dimes combined.
  2. Write Equation Based: Let's write the equation based on the value of each coin. The value of qq quarters is 0.25q0.25q dollars, and the value of dd dimes is 0.10d0.10d dollars. The sum of these values should equal the total amount of money, which is $15.75\$15.75.
  3. Total Value Equation: The equation that represents the total value is: 0.25q+0.10d=15.750.25q + 0.10d = 15.75. This equation correctly represents the relationship between the number of quarters and dimes and the total amount of money.
