Help me please :( ! Kevin and christy both saved money for their class trip . Kevin saved the same amount each week . The total amount that Kevin saved at the end of every two weeks in shown in the table below .

D. Christy saved $3 per week more than Kevin.

Step-by-step explanation:

We already know how much Christy saves per week, because of the equation y = 26x. She saves $26 per week.

To find Kevin's per week savings, divide y by x. I'll do (6, 138) as an example.

138 / 6

What multiple of 60 is closest to 138 without going over. That's 120.

138 - 120 = 18

Now we know the constant (k) is greater than 20.

18 / 6

6 goes into 18 three times.

20 + 3 = $23 per week.

$23/week is less than $26/week, so to say Kevin earned more than Christy in one week is wrong. As a result, A and C are out.

Now subtract 23 from 26 to get a $3 per week difference, which is D.

4th option is correct xy=-10

if this was to u plzz mark me the brainliest
