Bethany has 3 point 10 dollars in nickels and dimes. She has a total of 44 coins. What is the value of the nickels Bethany has?

Let n be the number of nickels and d the number of dimes. There are 44 coins, so n + d = 44; their total value is 310 cents, so 5n + 10d = 310, or n + 2d = 62. Subtracting the coin-count equation gives d = 18, so n = 26. The nickels are worth 26 × 5 = 130 cents, or $1.30, which is choice B.
