Answer :
The equation that shows how the total number of cups of ice used, y, depends on the number of glasses filled, x, is [tex]y = 0.8x + 80[/tex]
Linear function
Filling the cooler is an illustration of a linear function
A linear function is represented as: [tex]y = mx + b[/tex]
Where
- m represents the slope/rate
- b represents the y-intercept/the initial value
- x and y are the variables
The equations
By comparison, we have the following parameters
- [tex]m =0.8[/tex] --- the amount of cups per ice
- [tex]b = 80[/tex] ---- the initial amount of cup
So, the equation that represents this scenario is
[tex]y = 0.8x + 80[/tex]
