Answer: She deposits 50 dollars per month right? But as known her parents deposited her 2,500. So, it will take her 50 months to complete the amount of 5000 dollars needed for college.
Step-by-step explanation: Im not good with equations but here we go.
First: AS we know the account already had 2,500, and every month she deposits 50$.
What we can do is to divide 2,500 divided by 50 which will be 50.
Answer:
b. Non-proportional
Step-by-step explanation:
A table of values that represents a proportional relationship will have the same ratio of every pair in the given table. That is, y/x will result in the same value all through for every given pair.
The table of values given does not show a proportional relationship, because the ratio of y to x of each given pair of values are different and unequal:
y/x = 3/1 ≠ 5/2 ≠ 7/3 ≠ 9/4
Therefore, it is non-proportional.
hope i help
