Example Question #662 : Isee Lower Level (Grades 5 6) Quantitative Reasoning

Brad is buying two appliances from a store: a microwave that costs $30 and a toaster that costs $25. He has two coupons: 10 percent off 1 item, and $5 off one item. 

What is the most money that he can save with these coupons (in dollars)?

Possible Answers:

Correct answer:

Explanation:

If Brad has 2 coupons, 10 percent off 1 item, and $5 off one item, he should use the 10 percent off coupon on the more expensive item to save more money. 

Since the $30 microwave is more expensive, he should use the 10 percent off coupon on this item. This will save him $3 because 10 percent of $30 is $3. 

He can then use the $5 off coupon on the $25 toaster, which saves him $5. 

Therefore, the total savings is $8.

Example Question #664 : Isee Lower Level (Grades 5 6) Quantitative Reasoning

Amanda and Adriana each ran four laps around the track in twelve minutes. At the same rate of speed, how long would they need to run twenty-eight laps?

Possible Answers:

Correct answer:

Explanation:

To solve this problem, one must first determine how long it takes to run one lap. Since it takes twelve minutes to run four laps, divide twelve by four.

It takes three minutes to run one lap. 

To determine how long it will take to run twenty-eight laps, multiply the original rate of speed by the new distance.

It will take eighty-four minutes to run twenty-eight laps if each lap is run in three minutes.

Example Question #1 : How To Find The Distributive Property

Which expression demonstrates the Distributive Property?

Possible Answers:

\dpi{100} 2\times 1=2

\dpi{100} 2+4=4+2

\dpi{100} 2(4+3)=(2\times 4)+(2\times 3)

\dpi{100} 2+3+4=3+2+4

Correct answer:

\dpi{100} 2(4+3)=(2\times 4)+(2\times 3)

Explanation:

The distributive property involves multiplying each term inside of the parentheses by the term outside of the parentheses.  The distributive property is:

\dpi{100} a(b+c)=(a\times b)+(b\times c)
