The tax added to $220 is solved by 220 X .0725 = 15.95. Add 15.95 to $220 and get $235.95. The tip (assuming it is 20% after tax ) is $235.95 X .20= $47.19
Add the $47.19 to $235.95= $283.14
93 is not a multiple of 9. Multiple of 9 would be 90 or 99. These are multiples of 9 in a range from 0 up to 100:
9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99
Answer:
x=5
Step-by-step explanation:
Step 1: you want to have x alone on one side so I will subtract one x from both sides (to remove the 1 x on the right side). Now we're left with 3x=15.
Step 2: Divide both sides by 3 (to remove the 3 in front of 3x). Now we have x=5.
