Answer:
14 dimes and 4 quarters
Step-by-step explanation:
x= number of dimes
y=number of quarters
x-10=y
0.10x+0.25y=2.40
substitute for y
0.10x+0.25(x-10)=2.40
0.35x-2.50=2.40
0.35x=4.90
x=14
y=4
the answer to your equation is 25, because 17 if 68 is 25

Answer:
45+10x = y
Step-by-step explanation:
$45 -- stays the same no matter what so that's constant.
$10 -- this varies dependent on the number of vaccinations your dog needs, so you'd use a variable to represent the number of vaccinations (in this case I'm using variable "x").
So, for example if your dog needed 7 vaccinations, it would be: 45+10(7) = y -- answer being $115.
