Question

Over a period of months, milk went from $2 per gallon to $3.50 per gallon.

Which percent shows the new price of milk in relation to the old price of milk?

A. 1.5 %
B. 15%
C. 150%
D. 175%

Answer 1

Answer D is correct

Explanation:

To calculate the percent increase in price, we can use the following formula:

`\sf Percent \:increase = ((New\: price - Old \:price))/( Old \:price) * 100`

In this case, the old price of milk is $2 per gallon, and the new price is $3.50 per gallon.

Let's calculate the percent increase

`\sf Percentage\: increase \\\\=\frac{ (3.50 - 2) } {2} * 100\\\\ =(1.50 )/( 2) * 100\\\\= 0.75 * 100\\\\= 75`

Therefore, the new price of milk is 75% higher than the old price.

∴ 100 + 75 = 175

Answer 2

• D. 175%

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

The new price in terms of the old price is:

• 3.50/2 * 100% =
• 1.75 * 100% =
• 175%

The matching choice is D.
