PLEASE HELP :(
Taisha uses the elliptical cross-trainer at the gym. Her general goal is to burn 280 calories per workout, but she varies by as much as 25 calories from this amount on any given day. Write and solve an equation to find the maximum and minimum number of Calories Taisha burns on the cross-trainer.

To solve this problem, we can use the fact that Taisha's goal of burning 280 calories varies by as much as 25 calories.
Let's assume that the maximum number of calories burned by Taisha is denoted by x. According to the given information, her actual calories burned can be as high as 25 calories more than her goal. Therefore, we can write the equation:
x = 280 + 25
Simplifying this equation, we get:
x = 305
So, the maximum number of calories Taisha can burn on the cross-trainer is 305 calories.
Similarly, let's assume that the minimum number of calories burned by Taisha is denoted by y. According to the given information, her actual calories burned can be as low as 25 calories less than her goal. We can write the equation:
y = 280 - 25
Simplifying this equation, we get:
y = 255
So, the minimum number of calories Taisha can burn on the cross-trainer is 255 calories.
