Answer:
a. C = $ 10.50x b. 2 persons
Step-by-step explanation:
a. Write an equation to find how many people visited in a hour
Let x be the number of persons admitted in one hour. Since the movie theater charges 10.50 per person for admission, then the total admission fees would be C = charge per person × number of persons = $ 10.50 × x = $ 10.50x.
C = $ 10.50x
b. Solve an equation to find how many people visited in a hour
Given that C = $19.11, and C = $ 10.50x, so,
x = C/($10.50)
substituting C into the equation, we have
x = $19.11/$10.50
x = 1.82
Since we cannot have a decimal number of persons, x is rounded up to the nearest whole number. So,
x = 1.82
x ≅ 2
So, two people visited the theater in one hour.
Answer:
n = -2
Step-by-step explanation:
we apply distributive property:
-4(8+5n)=8
-4*8 -4*5n = 8
we have:
-32 -20n = 8
we add 32 to both sides of the equation:
-32+32 -20n = 8 +32
we have:
-20n = 40
we divide by -20 to both sides of the equation:
-20n/-20 = 40/-20
we have:
n = -40/20
finally we have:
n = -2
