"X is partly constant and partly varies as y"
---> x = ky + p
when y=2,x=30 ---> 30 = 2k + p
when y=6,x=50 ---> 50 = 6k + p
subtract: 20 = 4k
k = 5
sub back in the first: 30 = 10+p
p = 20
x = 5y + 20
now you can answer B
notice this is just a variation of y = mx + b

Answer:
5
Step-by-step explanation:
Answer is x+9=11
6+x=9
x=3
15=x+12
x=3
7+x=10
x=3
x+9=11
x=2
So x+9=11 has a different x value than the rest of the equations. So it doesn't belong with the other three.
By using basic concept of percentage we got that minimum payment on Card E is 0.77 than on Card D.
<h3>What is percentage ?</h3>
Percentage is a number or ratio expressed as a fraction of 100.
Here given that
Marilyn has two credit cards, D and E. Card D has a balance of $691. 64, and Card E has a balance of $1,014. 22. The minimum monthly payment on Card D is 3. 57% of the total balance, and the minimum monthly payment on Card E is 2. 51% of the total balance
So minimum balance of Card D is 3.57 Percentage of $ 691.64

minimum balance of Card E is 2. 51 Percentage of $1,014. 22.

Now we can see that minimum balance of Card E is 25.49-24.69=0.77 extra that on D
By using basic concept of percentage we got that minimum payment on Card E is 0.77 than on Card D.
