If half of the cards were sold and 172 cards were left, how many cards were originally printed?

• 172

• 344

• 516

• 688

In the card problem, what is the first step to set up the algebraic equation?

• Set 172 as half of the total number of cards

• Divide the total number of cards by 2

• Subtract 172 from the total number of cards

• Multiply the total number of cards by 2

What is the algebraic equation used to solve the card problem?

• 1/2 * X = 172

• X + 172 = 1/2

• X - 172 = 1/2

• 2 * X = 172

If one-third of university students wanted to become teachers and 3,360 did not, how many total students were there?

• 5,040

• 3,360

• 10,080

• 1,120

In the university students problem, what fraction of students did not want to become teachers?

• 3/4

• 2/3

• 1/3

• 1/2

What is the first step to solve the university students problem algebraically?

• Multiply both sides by 3

• Subtract 3,360 from the total

• Multiply both sides by 2

• Divide both sides by 3

What is the total number of students if 3,360 did not want to become teachers and this represents two-thirds of the total?

• 15,120

• 10,080

• 6,720

• 5,040

In the decimal multiplier problem, what is the multiplier used?

• 0.9

• 34.7197175

• 1.5

• 2.3

What is the final step to solve for X in the decimal multiplier problem?

• Subtract 0.9

• Add 0.9

• Divide by 0.9

• Multiply by 0.9
