Answer:
Raven should buy the boots at LaceUp since total cost is lower ($77.54)
Step-by-step explanation:
price of the boots at Shoe Town:
[$85.95 x (1 - 15%)] x (1 + 7.16%) = $73.06 x 1.0716 = $78.29
price of the boots at LaceUp:
{[$85.95 x (1 - 10%)] - $5} x (1 + 7.16%) = ($77.36 - $5) x 1.0716 = $72.36 x 1.0716 = $77.54
price of the boots at Run, Don't Walk (online store):
$71.99 + $6.50 = $78.49
x= 9
y= 9
4x -2y= 18.................equation 1
-4x + 2y= -18...............equation 2
From equation 1
4x= 18 + 2y
x= 18 + 2y/4
substitute 18+2y/4 for x in equation 2
-4(18+2y/4) -2y= 18
-(18+2y)-2y= 18
-18-2y-2y= 18
-18+4y= 18
4y= 18+18
4y= 36
y= 36/4
y= 9
Substitute 9 for y in equation 1
4x-2y= 18
4x-2(9)= 18
4x-18= 18
4x= 18+18
4x= 36
x= 36/4
x= 9
Hence the value of x is 9 and the value of y is 9
