A snack machine accepts only quarters. Candy bars cost ¢25, each piece of chocolate costs ¢75, and a pack of juice costs ¢50. How many quarters are needed to buy three candy bars, two pieces of chocolate, and one pack of juice?
Three candy bars cost ¢25 x 3 = ¢
<gadget id="calculator">25*3</gadget>
<output>75</output>
75.
Two pieces of chocolate cost ¢75 x 2 = ¢
<gadget id="calculator">75*2</gadget>
<output>150</output>
150.
So, the total amount needed to buy those is ¢75 + ¢150 + ¢50 = ¢
<gadget id="calculator">75+150+50</gadget>
<output>275</output>
275.
Since a quarter is equal to ¢25, therefore ¢275/¢25 = 
<gadget id="calculator">275/25</gadget>
<output>11</output>
11 quarters are needed.
