It says to round to the nearest whole number so it would be A. or D. In the end It would be D. because 22.73 is closer to 23 then 22.
Direct variations take the form y=kx. We need to solve for y in order to find k.
<span>3x+5y=0 </span>
<span>5y=-3x </span>
<span>y=(-3/5)*x </span>
<span>k=-3/5.</span>

Answer:
what are the options?!? you should tell us so I can help
A) let x=months let y=cost
y=mx+b
y= 20x+ 60
Remember 20 is the variable which means in this case every month it cost 20$ and 60 is the constant which means you only pay it once
B) let x= Months let y= cost
y=10x + 150
C) platinum gym
y= 20x+60
y=20(1)+60
y=20+60
y=80
Superfit
y=10x+150
y=10(1)+150
y=10+150
y=160
Therefore Tom will pay less after the first month
D) y=y solve for x
y=20x+60
y=10x+150
20x+60=10x+150
-10x. -10x
10x+ 60=150
-60. -60
10x=90
10x/10=90/10
X=9
9 months
Pick any equation and sub in x
Y=10x+150
Y=10(9)+150
Y=90+150
Y=240
240$
Know that you only have to do one equation to find y but if you want to show both you can
Therefore there is a period where Tom and Edward paid the same amount, after nine months they would both pay $240
E) if they plan on going to the gym 9 months and less the best deal gym is platinum gym but if they want to go for more then 9 months then the best deal gym is super fit
