If the point of the assignment is to get the most amount of cheese per dollar the answer is a.
You just divide the price with the number of ounces you buy and that will give you the price per ounce.
a = 5/(4*5) = $0.25 per ounce
b = 3.24/12 = $0.27 per ounce
c = 4.19/16 = 0.261875
therefore a is the best bang for the buck
Hope this helps :)
All of these only require a single operation before you get x alone. for example:
x - 2 = 6
compared with
2x = 6
for the first one, you add two and get x = 8. for the second one, you divide by 2 and get x = 3. they're both a single step, as the name "one-step" equations tells you, and you only have to divide, multiply, add, or subtract one value.
The answer to the question is 26°

Answer:
There are 1240 students at Washington middle school.
Step-by-step explanation:
Percentages and Portions
We can find portions of a whole by correctly managing the percentages of each part. We know 25% of all students at Washington middle school were on the honor roll. From that portion, 60% of the students are seventh graders. That means 40% of the 25% are eight graders, i.e. 40*25%=10% were from eight grade.
We have 10% of all students are 124, thus the number of students are 124/10%=1240
There are 1240 students at Washington middle school.
Let's test the answer. 25% of 1240 students are on the honor roll, which is 310 students. 40% of 310 students are from 8th grade, 40%*310 = 124 as stated in the problem
