The video tutorial covers two word problems that involve forming and solving equations. The first problem deals with finding four consecutive odd integers whose sum is 840. The solution involves defining a variable for the smallest integer and forming an equation to solve for it. The second problem involves calculating the number of minutes used in a cell phone plan with a fixed monthly rate and a variable rate per minute. The solution involves setting up an equation to find the total minutes used.

How do you express the sum of four consecutive odd integers starting from n?

• n + (n + 2) + (n + 4) + (n + 6)

• n + (n + 4) + (n + 8) + (n + 12)

• n + (n + 1) + (n + 2) + (n + 3)

• n + (n + 3) + (n + 6) + (n + 9)

If Mr. T's cell phone bill was $59.40, what is the equation to find the number of minutes he talked?

• 30 + 0.05t = 59.40

• 30 + 0.06t = 59.40

• 30 + 0.07t = 59.40

• 30 + 0.08t = 59.40

What is the first step in solving the cell phone bill equation?

• Multiply both sides by 0.07

• Subtract 30 from both sides

• Add 30 to both sides

• Divide both sides by 0.07

After subtracting 30 from both sides, what is the next step in solving 0.07t = 29.40?

• Subtract 0.07 from both sides

• Multiply both sides by 0.07

• Divide both sides by 0.07

• Add 0.07 to both sides
