Re: The price of gasoline at a service station increased from $1.65 per ga [#permalink]
To find out how much more Sally will pay this week for the same amount of gasoline, we need to calculate the difference in cost per gallon and then multiply it by the number of gallons she purchased last week.

The price of gasoline increased from $1.65 per gallon to $1.82 per gallon, which is an increase of $1.82 - $1.65 = $0.17 per gallon.

Sally paid $26.40 last week for gasoline, and we need to find out how much more she will pay this week. To do that, we divide $26.40 by the price per gallon last week ($1.65) to find the number of gallons she purchased: $26.40 / $1.65 = 16 gallons.

Now, we can calculate how much more Sally will pay this week by multiplying the increase in cost per gallon ($0.17) by the number of gallons (16):

$0.17 * 16 = $2.72

Therefore, Sally will pay $2.72 more this week for the same amount of gasoline.

The answer is (D) $2.72.

Re: The price of gasoline at a service station increased from $1.65 per ga [#permalink]
To find out how much more Sally will pay this week for the same amount of gasoline, we need to know how many gallons of gasoline she bought last week. We can find this out by dividing the amount she paid by the price per gallon:

$26.40 ÷ $1.65/gallon = 16 gallons

So Sally bought 16 gallons of gasoline last week.

This week, the price is $1.82 per gallon, so to find out how much Sally will pay for 16 gallons, we multiply the price per gallon by the number of gallons:

$1.82/gallon × 16 gallons = $29.12

Therefore, Sally will pay $29.12 - $26.40 = $2.72 more this week for the same amount of gasoline.

The answer is (D) $2.72.

Re: The price of gasoline at a service station increased from $1.65 per ga [#permalink]
After reading the answer, we can go through the options.
As given, increase in the price of gasoline is 0.17 dollars. So the options will be multiple of 0.17 or 17.
In this manner, we can eliminate option B and D.
Next, we need to know the qty of gasoline bought at initial price. Same qty is bought after price increase.
Let l be the qty of gasoline.
l= 26.4/1.65 (approx. 25/1.5)= 16
Clearly A is not multiple of 16, therefore eliminated.

We see that 2.64 and 2.72 is close to 16^2= 256. Add 16 to 256, we get 272. Hence, the answer D.
