That is called an equation
Answer:
1 and 4
Step-by-step explanation:
Answer: 0
Step-by-step explanation:
Let statements :
Let x be the number of tickets sold for an adult
Let y be the number of tickets sold for a child
Equations :
x + y = 280 OR y = 280 - x
4x + 2y = 1320
Substitution (sub the 2 equations in together) :
4x + 2(280 - x) = 1320
4x + 560 - 2x = 1320
2x = 1320 - 560
x = 760/2
x = 380
x is the number of tickets sold for the adults. meaning that 380 adults went.
Find the # of children :
x + y = 380
we know that x = 380
380 + y = 380
y = 380 - 380
y = 0
Conclusion :
No children went because the movie was rated R. Only adults attended.
Answer:
The rate of change with respect to monthly sales is 4000 - 200t.
Step-by-step explanation:
The sales per month (monthly sales) of the new sound system being sold by Sunny Electronics is given by q(t) = 4000t - 100
units per month, where t is number of months from the introduction of the sound system.
The price of each unit of the sound system charged by Sunny Electronics is given by p(t) = 2000 - .
The rate of change with respect to monthly sales will be given by the equation
.
Answer:
$136.50
Step-by-step explanation:
Time and a half = 13.00 + (13 × 1/2)
Time and a half = 13.00 + 6.50
Time and a half = $19.50
If he works 7 hours of overtime, and overtime means getting paid time and a half, we would multiply 7 hours by $19.50 to find the total amount he was paid
7 × 19.50 = 136.50
In overtime, he was paid $136.50
