Answer:
Total cost= $39
Step-by-step explanation:
Giving the following information:
At the theater, they sell a bag of popcorn for $5.50 and a drink for $3.75.
<u>First, we will establish the total cost formula:</u>
Total cost= 5.5p + 3.75d
p= number of bags of popcorn
d= number of drinks
<u>Now, for 3 bags and 6 drinks:</u>
Total cost= 5.5*3 + 3.75*6
Total cost= $39
Fraction form: 1/8
Decimal form: 0.125
Answer:
Step-by-step explanation:
Solve the system:
8x−4y=20
4x−8y=4
Reduce the first equation by dividing every term by -2:
-4x + 2y = -10
and then combine this result with the second equation:
4x−8y=4
-4x + 2y = -10
--------------------
-6y = -6, and so y = 1.
According to the first equation, if y = 1, then 4x - 8 = 4, or x = 3.
Then x = 3 and y = 1.
So, finally, x - y = 3 - 1 = 2
