Sample Test Item 1 (2005)

This is a classic business situation: buying items wholesale
and selling them for a retail price.
The Math Club buys the calendars wholesale for $2.00 and
retails them for $5.00. This is a profit of $3.00 per calendar.

If they sell all 150 calendars, then they will have:

Total Profit = $3.00 per calendar * 150 calendars = $450.00.

The correct answer is Choice B.

Sample Test Item 61 (2003)

This problem test to see if you can look at a situation and make some judgement calls.

The first judgement calls you need to make is the minimum and maximum possible distances Sean could have traveled.

If he drove for 6 hours at 55 MPH, then the minimum distance covered is 330 miles. This eliminates Choice A. This estimate is too low.

If he drove for 6 hours at 75 MPH, then the maximum distance covered is 450 miles. This eliminates Choice C because he was not driving 75 MPH during the entire journey. This also eliminates Choice D because that estimate is too high.

Only one choice remains. Choice B is the only reasonable distance Sean may have driven.

Sample Test Item 47 (2003)

1.87 * 10-1 oz = 0.187 oz

1.87 oz / 10 = 0.187 oz

Choice B is the correct answer.

Sample Test Item 46 (2003)

Rational numbers include fractions and decimals with repeated endings. They may also include integers.

(5,6,89,-33,-98)

Integers include negative numbers, positive numbers and zero.

(…-2,-1,0,1,2…)

The best way to represent the number of people is using whole numbers.

(1,2,3,4….)

Irrational numbers include square roots and numbers like p (pi).

(3.14159…..)

Irrational numbers cannot be classified as numbers representing the number of people in a room.

Choice D is the correct answer.

Sample Test Item 33 (2003)

2003-item33.png

The square root of 625 square feet can only be 25 feet.

The length cannot be negative so Choices A and C are not possible.

The square root of 625 square feet is NOT 625 feet. (makes no sense)

Your only possible choice is Choice B, which is the only correct answer.

Sample Test Item 12 (2003)

2003-item12.png

Looking at our choices, we know we can eliminate two obvious ones: Choice A, the distance between the sea level and the submarine and Choice D, the distance between the helicopter and sea level.

If the minumum distance between the helicopter and the submarine is the distance to sea level (4,500 feet) then Choice B is not possible.

The only choice we have is Choice C.

Sample Test Item 6 (2003)

2003-item6.png

Choice B is the sqrt(9).

Choice D is the sqrt(16).

Thus, Choice A is not a possible answer because it is less than the sqrt(9).

The only option is Choice C.

Sample Test Item 5 (2003)

2003-item5.png

Move the decimal point to the left until you reach 9.3; then count the number of zeroes. 7 zeroes.

The only choice is Choice C.
