$12.25 pen set; 60% discount

Mathematics

As you want a 60% discount, you must find 40% of $12.25.

40% of $12.25 is the same as 2/5 of $12.25.

Now, 12.25 / 5 = 2.45

And, 2.45 x 2 = 4.90

--------------

This means that 60% off $12.25 is $4.90.

A van travels 150 miles on 6 gallons of gas. How many gallons will it need to travel 325 miles?
shtirl [24]
<h3>Answer:  C) 13 gallons</h3>

============================================================

Work Shown:

(150 miles)/(6 gallons) = (325 miles)/(x gallons)

150/6 = 325/x

150*x = 6*325 .... see note below

150x = 1950

x = 1950/150 .... divide both sides by 150

x = 13 gallons is the final answer

-----------

Note: in this step, I cross multiplied. The general template for cross multiplication is that we go from A/B = C/D to A*D = B*C. As the name implies, the "cross" refers to the "X" shape that forms when you multiply the terms.
