3. nora works at a donut shop. at the end of her shift, the change in the tip jar
totals $13.05. the jar contains quarters dimes, and nickels. the number of
dimes is 3 more than twice the number of nickels and the number of quarters
is i less than three times the number of nickels. which system of equations
could be used to find the number of dimes in the jar?
a. 0.25 +0.104 +0.05n = 13.0
c. 0.259 +0.10d +0.05n = 13.05
d=3+2n
d= 3 +2n
q=1 - 3n
q=3n-1
b. 9+d+n= 13.05
d. 9+d+n= 13.05
d=3+27
n= 3+2d
q=3n-1
q=1-31
