First you add up al the original prices which is 2.50, 4.95, and 6.00 and you should get 13.45
Then you would do 13.45 times 20 and you should get 269 and now you divide 269 by 100 and that would be 2.69 and thats 20% off now take 13.45 your total subtracted by your 20% off which is 2.69 and you would get 10.76 and thats your total...... : / hope that helps
Answer:

Answer:
THEY ARE 37 AND 28
Step-by-step explanation:
LET THE NUMBERS BE X AND Y
X = 9 + Y
X - Y = 9 ........1
X + Y = 65 .....2
ADDING 1 AND 2
2X = 74
DIVIDING BY 2
2X/2 = 74/2
X = 37
AND X = 9 + Y
: Y = X - 9
PUTTING X = 37
Y = 37 - 9
Y = 28
