Can someone explain number five??

Remark

You have 40 dollars to spend.

<em><u>AT & T</u></em>

Let the number of minutes = M

A. 20 + 0.10*M ≤ 40  

B. 20 + 0.10*M ≤ 40     Subtract 20 from both sides.

20 - 20 + 0.10M ≤ 40 - 20

0.10M ≤ 20                   Divide by 0.10

0.10M/0.10 ≤20/0.10

M≤ 200 minutes.

Verizon

A

15 + ( M ≥ 300)*0.50 ≤ 40

B

15 + ( M ≥ 300)*0.50 ≤ 40                   Subtract 15 from both sides.

(M≥300)*0.50 ≤ 25

(M≥300) ≤ 50 minutes.

This last one is a good deal more complicated. What it means is that if you are under 300 minutes, you pay only 15 dollars. If you are over 300 minutes, you can only go 50 more minutes before over extend your budget.

Part  C

These are alike in that they have a flat rate associated with them and both have a budgeted amount that has to be obeyed.

They are quite different in what they offer. The second plan is for people who use their cell phone quite a bit. For people like us (emergency only), the first plan is much better. We would always be within our 40 dollar limit. We don't use our cell but maybe 10 - 15 minutes a month on average.

Part D

I can't answer this for you. It depends on where you live and who offers you the best coverage. I would pick the first one, but that doesn't mean that it would be best for you.

900% of it is 450 ?<br><br> please help with this
charle [14.2K]
900% of 450=4050

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 450 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 450 is 100%, so we can write it down as 450=100%.
4. We know, that x is 900% of the output value, so we can write it down as x=900%.
5. Now we have two simple equations:
1) 450=100%
2) x=900%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
450/x=100%/900%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 900% of 450

450/x=100/900
(450/x)*x=(100/900)*x - we multiply both sides of the equation by x
450=0.111111111111*x - we divide both sides of the equation by (0.111111111111) to get x
450/0.111111111111=x
4050=x
