A nurse needs to order exactly 1000 cm of medical tape in five colors, at least one roll each. Which combination works?

Rationale

1 Red, 2 Orange, 1 Yellow, 2 Green, 1 Blue is the correct combination.

This combination fulfills the requirement of ordering exactly 1000 cm of medical tape in five colors, with at least one roll of each color.

A (2 Red, 1 Orange, 2 Yellow, 2 Green, 1 Blue) YOUR ANSWER

This combination results in a total of 1800 cm of medical tape (2*200 + 1*200 + 2*200 + 2*200 + 1*200), which exceeds the needed 1000 cm.

B (3 Red, 1 Orange, 2 Yellow, 1 Green, 1 Blue) YOUR ANSWER

This combination results in 1600 cm of medical tape (3*200 + 1*200 + 2*200 + 1*200 + 1*200), which is more than the required 1000 cm.

C (1 Red, 2 Orange, 3 Yellow, 0 Green, 2 Blue) YOUR ANSWER

This combination results in 1600 cm of medical tape (1*200 + 2*200 + 3*200 + 0*200 + 2*200), exceeding the needed 1000 cm. Furthermore, it does not meet the requirement of having at least one roll of each color, as there is no Green roll.

D (1 Red, 2 Orange, 1 Yellow, 2 Green, 1 Blue) CORRECT

This combination results in exactly 1000 cm of medical tape (1*200 + 2*200 + 1*200 + 2*200 + 1*200) and includes at least one roll of each color, fulfilling all the requirements.

Conclusion

The nurse can order exactly 1000 cm of medical tape in five colors, with at least one roll of each color, by opting for the combination '1 Red, 2 Orange, 1 Yellow, 2 Green, 1 Blue'. All other combinations either exceed the required length of tape or do not include all five colors.
