Answ

$11.00

Step-by-step explanation:

A quick way to do this would be as follows: 1.10 ( 0.50*$20), or $11.00.

0.50($20) gives us the sale price (at half off); that's half of $20, or $10.

The total due is then $10 (item cost) plus $1 (tax), or $11

How do I solve this <br> t + 1 = -3

MrRa [10]

Solve for t. Simply sense its +1, do the opposite and minus 1 from both sides of the equation. +1 - 1 = 0; -3 -1 = -4. Therefore, t = -4 is the correct solution.
