No
Step-by-step explanation:
The ratio of the first school is 5/2. The ratio of the second school is 7/8.
Answer:
7th graders- 100 students
8th graders- 110 students
Step-by-step explanation:
Let the number of 8th graders be represented by x and 7th graders be represented by y
<u>Equation based on number</u>
There difference between 8th and 7th graders is 10 hence equation becomes
x-y=10
<u>Equation based on contribution</u>
While x contribute each $8 and y contribute each $5, the total contribution is $1380 hence the equation becomes
8x+5y=1380
<u>Combining equations</u>
Having the two simultaneous equations which are
x-y=10
8x+5y=1380
Solving the equations.
5x-5y=50
8x+5y=1380
------------------
13x=1430
x=1430/13=110
Therefore, 8th graders are 110. Since the 8th graders were 10 more than 7th graders, the 7th graders will be 110-10=100 students
y = 21
i might be wrong, sorry if i am!!
The cheaper trail mix would be the half pound bag. So take the price of the 1/3 bag and times it by 3 that equals $4.50 then check out the 1/2 lb bag and times it by 2 and it would equal $2.30. So you know the half pound bag is cheaper
