Concepts

A student computes the cost of 8 tickets at $12.75 each and gets
$1,020.00. Which estimate best shows this answer is wrong?

8 tickets at about $13 each should cost roughly $104, not over $1,000.

The answer has too many decimal places to be correct.

$1,020.00 is an even number, so it must be wrong.

There is no way to estimate this without doing the exact multiplication first.

Procedures

A diver is at $-45$ feet. The diver rises 18 feet, then descends 30
feet. What is the diver's final depth, in feet? (Use a negative
number for below the surface.)

Compute exactly: $1/3 + 1/3 + 1/3$ . Enter your answer as a whole
number or fraction.

A class of 20 students each owes $2.50 for supplies plus $1.50 for a
field trip. Using the distributive property, which expression
correctly gives the total amount owed?

$20 \times (2.50 + 1.50)$

$(20 \times 2.50) + 1.50$

$20 \times 2.50 \times 1.50$

$20 + 2.50 + 1.50$
