Understanding Linear Equations for Tuition Costs

The video tutorial explains how to derive a linear equation to represent tuition costs at a university from 1990 to 2005. It covers the calculation of the slope and intercept, and how to use the equation to predict future tuition costs. The tutorial also demonstrates how to determine the year when tuition will reach a specific amount.

What was the tuition cost per credit hour in 1990?

• $430

• $287

• $92

• $365

In the equation c = b + mx, what does 'b' represent?

• The slope

• The input variable

• The output variable

• The initial value

How many years after 1990 is the year 2005?

• 20 years

• 25 years

• 15 years

• 10 years

What is the slope of the linear equation representing tuition costs?

• $13

• $92

• $287

• $195

What is the linear equation for tuition costs derived in the video?

• c = 430 + 21x

• c = 92 + 13x

• c = 287 + 15x

• c = 13 + 92x

In what year will the tuition cost be $365 per credit hour?

• 2011

• 2016

• 1990

• 2005

How do you calculate the value of 'x' for the year 2011?

• Subtract 1990 from 2011

• Divide 2011 by 1990

• Multiply 1990 by 2011

• Add 1990 to 2011

What is the tuition cost per credit hour in 2011 according to the equation?

• $365

• $430

• $287

• $92

What is the value of 'x' when the tuition cost is $430?

• 13

• 21

• 26

• 15

In which year will the tuition cost be $430 per credit hour?

• 2016

• 2005

• 2011

• 1990
