Atarot card reader gets paid $90 for each deck he reads, and his goal is to earn $2340 reading tarot cards this month. if he has already read 3 decks this month, how many more decks must he read in order to reach his goal?

He must read 23 more to reach that goal.

Step-by-step explanation:

First we need to find how many he needs to read total. To find that, start by dividing the amount he needs to make by the amount he gets paid per deck.

2340/90 = 26

Now subtract the number that he has already read.

26 - 3 = 23

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
