Answer:
there are 1/4 cups of Super Grain Cereal in the mixture
Explanation:
Super Grain cereal provides 240 calories per cup. Thus, for s cups of Super Grain cereal, there will be 240s calories
Crunchy Grain cereal provides 210 calories per 3/4 cups. Thus, 210 ÷ 3/4 per cup.
210 ÷ 3/4 = 280 calories, For c cups of Crunchy Grain cereal, there will be 280c calories
Jennifer mixes c cups of Crunchy Grain cereal, having 280 calories and s cups of Super Grain cereal, having 240 calories to get a final 1 cup mixture containing 270 calories, which can be expressed mathematically as:
280c + 240s = 270 ------- eqn(1)
Since, s cups of Super Grain cereal and c cups of Crunchy Grain cereal equals 1 cup, of the final mixture
c + s = 1 ------- eqn(2)
from eqn(2),
c = 1 - s
substitute c = 1 - s into eqn(1)
280(1 - s) + 240s = 270
280 - 280s + 240s = 270
- 40s = 270 - 280
-40s = -10
s = (-10)/(-40)
s = 1/4
Therefore, there are 1/4 cups of Super Grain Cereal in the mixture

C knowing how to dissect a test and the questions
The instruction that should be included by the nurse is: There is the potential of decreased effectiveness of birth control pills while taking phenytoin.
<h3>What is an Instruction?</h3>
This refers to the set of actions that a person needs to take based on clearly defined information.
Hence, we can see that with the administration of phenytoin to a patient, the nurse in charge needs to make a discharge teaching plan for the patient and tell the person the potential of decreased effectiveness of birth control pills while taking phenytoin.
