Which is the better deal? 6 feet of wood for 2.95
or
5 feet of wood for 2.25

5 feet of wood for 2.23

because the unit rate for each foot of wood is .45  compared to getting 6 feet for 2.95. 2.23 plus .43 (the cost for one foot) would be 2.63 making the wood much cheaper than the  6 foot option.

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.
