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

Hello,

A nickel is $0.05
A dime is $0.10

Let's x the number of dimes
44-x the number of nickels

0.10*x+0.05*(44-x)=3.10
==>10x+5*(44-x)=310
==>10x-5x=310-5*44
==>5x=90
==>x=18
There are 18 dimes and 44-18=26 nickels having a value of 26*$0.05=$1.30

Answer B
