Bethany has $3.10 in nickels and dimes. she has a total of 44 coins. what is the value of the nickels bethany has? $0.90 $1.30 $1.80 $2.60

$1.30

Step-by-step explanation:

Nickels are worth 0.05 and dimes are worth 0.1. Let Bethany have n number of nickels and d number of dimes. We can setup 2 equations and solve them simultaneously.

"Bethany has $3.10 in nickels and dimes":

"She has a total of 44 coins":

We can now solve for d in the 2nd equation and substitute into 1st equation and get the number of nickels, n. So:

d = 44 - n

Now,

Hence, Bethany has 26 nickels. So value of all the nickels is 5 cents each multiplied by 26 = 5 * 26 = 130 cents. This is equal to $1.30
