Answer:
52
Step-by-step explanation:
Let "a" represent the number of adult tickets sold. Then revenue was ...
9.40a +5.40(151 -a) = $1023.40
4.00a + 815.40 = 1023.40
a = (1023.40 -815.40)/4.00 = 208/4 . . . . . subtract 815.40, divide by 4
a = 52
52 adult tickets were sold that day.
That's the same as 1.024 ÷ 10⁴
Each time we divide by 10 we move the decimal point one place to the left. If we have to we add zeros at the front.
1.024 ÷ 10⁴ = 0.1024 ÷ 10³ = 0.01024 ÷ 10² = 0.001024 ÷ 10 = 0.0001024
Answer: 0.0001024
Answer:
66.6 or about 67 is the average rate of change
Using substitution:
first you have to express one variable in terms of the other, in this we can express y in terms of x:
Since both expressions are equal to y, you have to equal both expressions like this:
Now you can solve the equation:
Knowing x=10, you can use any of the expressions we found before to find y. In this case I'm going to use y= -x+9 because it's simpler but boy should give you the same result
So, the answer is x=10 and y=-1
