Answer:

See a solution process below:

Explanation:

The statement "$50 give or take $15" means you can have anywhere from $50 - $15 to #$50 + $15#

#$50 - $15 = $35#

#$50 + $15 = $65#

We can let the amount of money in your wallet be represented by #w#

We can write a system of inequalities as:

#$35 <= w <= $65#
