The equation will be A(x) = 5 + 2x and the independent variable will be the number of coffee cups that are purchased.
<h3>How to calculate the equation</h3>
Since the program costs $5 per month which allows her to get a discounted coffee price of $2.5 per cup.
The independent variable x, represents the number of coffee cups purchased. The dependent variable is the total monthly cost.
The function is A(x) = 5 + 2x. The cost for 10 cups will be:
= 5 + 2x
= 5 + 2(10)
= 5 + 20
= 25

Answer:
x+3
Step-by-step explanation:
If it says "more" than its probably talking about addition
2x + y = 350
x + 2y = 475
3x + 3y = 825
x + y = 275
x = 275 - y
(plug back into first equation)
2(275 - y) + y = 350
550 - 2y + y = 350
550 - y = 350
-y =-200 or y = $200 (dog)
therefore, x = $75 (cats)
Check
2(75) + 200 = 350
75 + 400 = 475

Answer:
q=723 or something close to that
Step-by-step explanation:
First you subtract 12,000 from 21,853= 853
Second you divide that by 1.18 to get q by itself
Done.
Answer:
The answer should be around 1,149663 (Rounded off to the nearest whole number. Also if a population has a remainer you usually add it as 1. This is because these are people)
Step-by-step explanation:
First step involves listing the formulas being used:
600,000= population, 0.03= growth rate 22years= period
Therefore, we take the 600,000 and multiply by 1+0.03 ^22(to the power of 22 or period)
So, 600,000(1+0.03)^22
=1,149662.045 /1,149663
Hope this helps!
