Answer:
The answer is 408
Explanation:
20% of 510 is 102 and 510 - 102 is 408
A. To answer this question, we must consider two inequalities. The first inequality we will construct is regarding the number of tickets sold with respect to capacity. The theater cannot exceed the allotted 200 seats, so this would indicate we would use a less than or equal to inequality. The inequality we would construct to illustrate this using adult and child tickets is x + y <= 200.
The second inequality we will construct is based upon the ticket prices set and the theater’s goal. The problem indicates the theater wants to sell “at least $1,500 worth of tickets...” To create the inequality here, we will create it as follows: 12.5x + 6.25y >= 1,500.
To find the intersection point, we must isolate y. In order to do this, move x to the other side of both inequalities. Inequality 2 can be simplified to y >= -12.5x / 6.25 + 1,500 / 6.25. Graph and identify the solution from there.
'number' will be x
2x+3=7
subtract 3 on both sides:
2x=4
divide by 2 on both sides:
x=2
So the answer to the problem is A
Answer:
$700
Step-by-step explanation:
Given that:
Cost of desktop PC 10 years ago = $6000
Cost of desktop PC 2 years ago = $300
Linear model applies.
To find the rate of decrease per year, we need to find the slope.
One quantity is cost of PC here and second quantity here is number of years.
So, the answer is:
There is a decrease of <em>$700 </em>per year.
OR
Rate of decrease per year is <em>$700</em>.
