Calculating Costs of Sodas

The video tutorial explains how to calculate the total cost of sodas bought by Calvin, using variables C for Coca-Colas and M for Mountain Dees. Each soda costs $2.25. The total cost T can be expressed as 225C + 225M. Alternatively, the expression can be factored to 225(C + M).

What is the cost of each soda that Calvin buys?

• $1.50

• $2.00

• $2.25

• $3.00

Which variable represents the number of Mountain Dees Calvin buys?

• D

• T

• M

• C

What does the variable 'T' represent in the context of the problem?

• Total number of coca-colas

• Total number of sodas

• Total cost of sodas

• Total number of Mountain Dees

How would you calculate the cost if Calvin buys 5 coca-colas?

• 5 * 2.25

• 5 + 2.25

• 5 / 2.25

• 5 - 2.25

If Calvin buys 4 Mountain Dees, how is the cost calculated?

• 4 - 2.25

• 4 / 2.25

• 4 + 2.25

• 4 * 2.25

What is the expression for the total cost T of sodas Calvin buys?

• 225 + C + M

• 225C + 225M

• 2.25C + 2.25M

• C + M

What is one way to simplify the expression for total cost?

• Subtract 225 from C and M

• Factor out 2.25 and add C and M

• Add 225 to C and M

• Multiply C and M by 225

What is the alternative method to calculate the total cost?

• Subtract 225 from the total

• Multiply each soda by 225

• Factor out 225 and add C and M

• Add 225 to each soda

If Calvin buys 3 coca-colas and 2 Mountain Dees, what is the total cost?

• $11.25

• $12.75

• $10.00

• $13.50

What is the cost of buying 10 sodas, regardless of type?

• $25.00

• $22.50

• $20.25

• $27.50
