f^-1(x) = 2x + 10 → d
let y = x - 5
rearrange making x the subject
x - 5 = y
add 5 to both sides
x = y + 5
multiply both sides by 2
x = 2y + 10 ⇒ f^-1(x) = 2x + 10

Step-by-step explanation:
This is tricky to answer, but I'll do my best.
You cant subtract 3 from 0, unless you wish to go into the negatives.
So, you have to borrow from the 0s neighbor, who is in fact another 0.
So in order to help his neighbor, the middle number 0 borrows from his other neighbor, the number 5.
5 has some to spare, so he gives the middle 0 a 1, which turns himself into a 4 and that 0 into a 10.
Then the 10 gives the first 0 a 1, turning himself into a 9 and the first 0 into a 10.
It might be confusing, but thats how it works.

So you just need to divide the cost of 12 pack of soda by 12 pack of soda.
That would be $3.75 / 12 = $0.3125
So answer is $0.3125 per can of soda or you can round it to approximately $0.31 per can of soda.
Hope this helps.
