A shop sells a party hat at x dollars and a mask at y dollars. On a particular morning, 3 hats and 4 masks were sold for $27. In

Aleks [24]

Answer:

Cost of each hat: $5

Cost of each mask: $3

Step-by-step explanation:

Let be "x" the cost in dollars of a party hat and "y" the cost in dollars of a mask.

Set up a System of equations using the information given in the exercise:

$\left \{ {{3x+4y=27} \atop {3x+6y=33}} \right.$

You can use the Elimination Method to solve this System of equations:

1. You can multiply the first equation by -1.

2. Then you must add the equations.

3. Solve for "y".

Then:

$\left \{ {{-3x-4y=-27} \atop {3x+6y=33}} \right.\\.....................\\2y=6\\\\y=\frac{6}{2}\\\\y=3$

4. Now you can substitute the value of "y" into any original equation.

5. Finally, solve for "x" in order to find its value.

Then:

$3x+4(3)=27\\\\3x=27-12\\\\x=\frac{15}{3}\\\\x=5$

The school band is comprised of middle school students

iogann1982 [59]

Answer:if there are 7 HS students for every 2 MS students and there are 18 MS students...

18/2 = 9

9(7) = 63

So, there are 18 + 63 = 81 total students.

Since we had 9 parts last year also (1:8), 81/9 = 9 students are in each part. 8 students in each part are HS and one is MS.

8(9) = 72 HS students last year.

72 - 63 = 9 fewer HS students than last year.

Hope this helps!
