Step-by-step explanation:
0.6x- 1.2x = 6
-0.6x = 6
x = 6/0.6
x = -10
All you should have to do is take 180-95 to get 85 for x & then take 85+45= 130 - 180 = 50.
x=85 & y=50
Answer:
$82.16
Step-by-step explanation:
78.25 * .20 = 15.65 as a tip,
78.25 *.15 = 11.74 as the discount, subtract from initial value:
78.25 - 11.74 = 66.51
then add the tip: 15.65 + 66.51 = $82.16
