Create and solve equations, showing your work. You must create the equations and show the steps required to solve them.

Your portfolio must include a minimum of the following types of equations:

One one-step equation

One equation that contains fractions

One equation with decimals

One real-world problem that is solved by an equation

One step equation, where only one step is required to solve the problem. Example:

20 = 5x

4 = x

Fractions:

1/2 + x = 3/2

x = 3/2 - 1/2

x = 1

Decimals:

0.5 + x = 1.5

x = 1.5 - 0.5

x = 1

Real world problem: (word problem and equation)

It costs $5 per hour to rent a canoe plus a $3 rental fee. How much will the total be if you plan on renting the canoe for 3 hours?

y = 5x + 3

y = total cost; x = number of hours rented

y = 5*3 + 3

y = 15 + 3

y = $18
