The diagram below shows the number of ice cream cones sold in a day at a local ice cream shop. Based on these results what is the most reasonable prediction of the number of chocolate chip ice cream cones that will be sold out of the next 240 cones sold?

B-60

EXPLANATION:

If he sold 8 vanilla, 28 double scoop and 12 chocolate chip, it means he sold 12 chocolate chip out of 48. So he sold 12/48 chocolate chip, which equals 1/4. If we write it in percentages, we will see that 1/4•100%=25%. Now we need to know how many chocolate chips would be sold in next 240 cones. In conclusion, we need to calculate 25% of 240. So if 240 is 100% and X is 25%, then 240•25=100X. If we solve that equation, we will see that X=60, so 25% of 240 equals 60. In conclusion, the right answer is B.
