Question

Julia has a jar that contains a mixture of dimes and pennies. She reaches into the jar without looking and selected a coin. She repeats this process 14 times, which result 8 dimes and 6 pennies. Based on these results, about how many pennies can she expect if she randomly select a total of 70 coin
A.24
B.30
C.40
D.53

Answer 1

Hello there,

So within 14 times, she had 8 dimes and 6 pennies.

We could just add 14 until we reach 70 and that was 5.

So we multiply both the dimes and pennies there would be 48 dimes and 30 pennies in a trial of 70 times.

Therefore your answer is B

Answer 2

It is 30.

70/14=5
5x6=30
Hope this helps
