Three posters cost $9.60. at that rate, how many posters can you buy for $48? a) 5 posters b) 15 posters c) 16 posters d) 13 posters

Hey there.

Since 3 posters cost $9.60, let's try to see how much one poster costs. That way, we can determine how much $48 will get us.

To solve for the price of one poster, let's divide our total given cost by how many posters were bought;
$9.60 / 3 = $3.20

$3.20 is the price for one poster.

Now, let's divide our total given price, $48, by 3.20 to solve for how many posters we can by. The nearest whole number will be our answer (decimals do not count since you cannot by part of a poster).

48 / 3.20 = 15

This quotient determines our  $48 will buy you 15 posters.

Your correct answer is answer choice "B.) 15 posters."

I hope this helps!
