Well 4 divided by 3 is 1.33333... So I hope that helps x
number of messages she can send and receive so the unlimited plan is cheaper than paying for each message
<em><u>Solution:</u></em>
Natalie can send or receive a text message for $0.15
Natalie can get an unlimited number for $5
To find: Number of messages she can send and receive so the unlimited plan is cheaper than paying for each message
Let "x" be the number of messages
Cost for sending and receiving message = $ 0.15
Cost for unlimited plan = $ 5
Then, according to given, we frame a inequality as:
The condition is: unlimited plan is cheaper than paying for each message
Therefore,
(number of messages)(Cost for sending and receiving message) is greater than or equal to Cost for unlimited plan
Thus for messages ,the unlimited plan is cheaper than paying for each message
Compounded anually means
if you put x in at y percent then
you calculate like this
if you put in x at y percent then the money you earn is
x +(x times y)=z=first year
second year=z+(z times y)=s
third year=s+(s times y)=t
percent means parts out of 100 so 5%=5/100=0.05
'of' can be translated as multiply
so
3000 +(3000 times 0.05)=3150=fisrt year
3150+(3150 times 0.05)=3307.5=second year
3307.5 +(3307.5 times 0.05)=3472.88=tird year
he will have 3472.88 at end of 3 years
The combined mass would be the sum of the 2 masses.
This is an answer to an addition problem.
15 kg + 13 kg = 28 kg
The combined masses would be 28 kg.
