Answer: 19
Step-by-step explanation: let the number of candies left in the bag be y and the number of minutes eating be x.
Because she eats 5 candies per minute
0.05n + 0.1d = 3.10
n + d = 44
d = 44 - n
Substituting to the first equation:
0.05n + 0.1(44 - n) = 3.10
0.05n + 4.4 - 0.1n = 3.10
-0.05n = 3.10 - 4.4
n = 26
Obtaining the value of nickels:
26 * 0.05 = 1.3
Therefore, the value of nickels that Bethany has is $1.30
