Answer:
You can tell because, as x increases/decreases, y increases/decreases at the same rate EACH TIME. This way, no matter how many times the proportions increase OR decrease, the ratio between x and y always stays the same.
She has 65 water bottles....and she is buying boxes of water bottles (x) that hold 16 water bottles each. She can only buy up to 5 water bottles.
f(x) = 16x + 65...where f(x) = total water bottles and x = number of boxes
x < = 5.....here is ur restriction
the range is ur f(x) values which represent the total number of water bottles...keep in mind, she can only buy 5. Therefore, the numbers that can be subbing in for x are 0 thru 5.
So when subbing in 0 thru 5 for x, the results for f(x) are :
{ 65,81,97,113,129 } <== ur range
304.25 - 149 = 155.25
Now, how many songs can you buy with $155.25?
155.25 ÷ 1.15 = 135
So, you'll be able to buy 135 songs with the remainder of your earnings.
And that answers your question! :)
Answer:
Interest= $423.59
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= $6,000
Number of periods (n)= 3 years
Interest rate (i)= 2.3% = 0.023
<u>To calculate the Future Value, we need to use the following formula:</u>
FV= PV*(1+i)^n
FV= 6,000*(1.023^3)
FV= $6,423.59
<u>Now, the interest earned:</u>
<u />
Interest= 6,423.59 - 6,000
Interest= $423.59
Since these are alternate interior angles, they are equal. So, you would set them equal to each other (-5+13x=60). Then, add 5 to both sides to get 13x=65. Divide 65 by 13 to get the final answer, x=5
