Josie bought four lollipops for 65 cents each. She paid with a five-dollar bill. How many cents will she get back?
Murrr4er [49]

Answer:

240 cents

Step-by-step explanation:

Given that,

cost of one lollipop = 65 cents

total amount Josie need to paid = 65 * 4 cents = 260 cents

amount Josie gave  = $5

As we know

$1 = 100 cents

$5 = 100 * 5 cents

    = 500 cents

number of cents Josie will get back

500 - 260

240 cents or $2.40

So, Josie will get 240 cents back
