Without actually solving the problem, choose the correct solution by deciding which choice satisfies the given conditions. Kesha has a total of 100 coins, all of which are either dimes or quarters. The total value of the coins is $14.50. Find the number of each type of coin.
Which choice satisfies the given conditions?
O A. 70 dimes, 30 quarters
B. 20 dimes, 80 quarters
C. 40 dimes, 42 quarters

A. 70 dimes, 30 quarters

Step-by-step explanation:

Only options A and B create a total of 100 coins. It cannot be option B because 80 quarters by itself, is already over $14.50.
