1/3x - 2 = 1/4x + 11....it looks to me like one y was subbed in for another...
ur 2 equations are :
y = 1/3x - 2 and y = 1/4x + 11...but we need them in standard form...
y = 1/3x - 2
-1/3x + y = -2 ..multiply by 3
-x + 3y = -6.....or 3y - x = -6 <==
y = 1/4x + 11
-1/4x + y = 11 ...multiply by 4
-x + 4y = 44 or 4y - x = 44 <==
You multiply the 4.00 by 0.10 to get the 10% discount amount. Then you subtract that from $4.00. Then you multiply that amount by 1.06 to get the total with the 6% sales tax. To get $3.82 rounded to the nearest cent.
