Answer:
Step-by-step explanation:
Part A
Cost = T - (15/100) * T
Cost = (85/100)*T
Part B
You are asked to take 15% off the cost of something. The first equation is very clear how to do that -- just take 15% of T away from T
The second part is not so obvious if you are not familiar with it, but the result will be the same.
Start with the first equation
Cost = T - (15/100) T Change 1 T to 100 / 100
Cost = 100*T/100T - 15/100T
Cost = 85 /100 * T
Part C
Cost = Phone - 14 at Top quality. Red in Graph below
Cost = 75/100 * Phone at Big value. Blue in Graph belos
The graph below is a good way to answer this. I won't solve it algebraically when the graph will give you a much better idea which phone to get.
Answer: Up to a phone cost of 55 dollars, the red phone is the better buy.
After 55$ the blue phone is better.
Try this with a couple of values for phone,
The equation that shows how the total number of cups of ice used, y, depends on the number of glasses filled, x, is
Filling the cooler is an illustration of a linear function
A linear function is represented as:
Where
- m represents the slope/rate
- b represents the y-intercept/the initial value
- x and y are the variables
By comparison, we have the following parameters
--- the amount of cups per ice
---- the initial amount of cup
So, the equation that represents this scenario is
