Let x represent the amount of money in your wallet.
The money you may have in the wallet is $20 give or take $5, you can symbolize this as:
$20 ± $5 → you can expend the expression and write it as an inequation:
$20-$5 ≤ x ≤ $20+$5
Solve the calculations to determine the values of the possible amount in your wallet:
$15 ≤ x ≤ $25
The possible amount of money in the wallet is between $15 and $20, the movie ticket costs $12.95 which is less than the possible amounts.
You can afford to pay for the movie ticket.
