y= 1.25x+6.75
Make 31.75 y because that is the total cost he paid.
1.25x+6.75=31.75
1.25x=25
x=20
So he had 20 refills.
Simple...
you have: For every 14 seeds that Okra seeds Dana planted 9 of them grew; if he planted 182 seeds..how many grew?
Set up an equation...

Cross multiply....
14*x=14x
9*182=1638
14x=1638

x=117
This means that, for 182 seeds planted, 117 of them grew to be plants.
Thus, your answer.
The answer would be C (17/6)
This is because;
6 goes into 17 twice leaving a reminder of 5.
44x10^-2
or in other words
44 times 10 to the -2nd power
