Answer:
The answer matches with option A.
Step-by-step explanation:
We have to find the product of 100,000 and 1,000,000 using scientific notations.
Now, 100,000 can be written as 
and
1,000,000 can also be written as 
.
So, the product will give
100,000 × 1,000,000
= 
= 
= 
So, the answer matches with option A. (Answer)
In order to do this you need a system of equations. One equation is going to be about the numbers of people, the other is going to be about the money: what it costs for each type of person and the total amount of money earned. Money and numbers of people are 2 different things so they have to be in 2 different equations. We know that there were children and adults that went to the park and that the total NUMBER of people is 220. That means that adults plus children equal 220 people total. Or, in equation form, a + c = 220. Now the money part. Each child costs 2.25, so the cost of a child is 2.25c; each adult costs 6.20, so the cost of an adult is 6.20a. The total amount of money earned was 890. That equation is 2.25c + 6.20a = 890. Solve the first equation for a: a = 220 - c. Now sub in that value for a in the money equation, like this: 2.25c + 6.20(220-c) = 890. Solve this for c. 2.25c+1364-6.2c = 890. Combine like terms to get -3.95c = -474. Divide both sides by 3.95 to get that c = 120. There were 120 children out of the 220 people that attended. That means that there were 220-120 adults, or 100 adults. There you go!
The true statement about the inequality is that Total sales per day is greater than $250
<h3>How to write and solve inequality equation?</h3>
- Amount earned per day = 25 + 5% of x
= 25 + 0.05x
- Thursday = 4th day of the week
The inequality:
4(25 + 0.05x) > 50
100 + 0.2x > 50
100 - 50 > 0.2x
50 > 0.2x
x > 50/0.2
x > $250
