Answer:

r=1

Step-by-step explanation:

-7.61 - 4.3r = -8.1r - 3.81

(bring like terms to one side)

-4.3 r = -8.1r -3.81 + 7.61

-4.3r + 8.1 r =-3.81 + 7.61

(consolodate)

3.8r = 3.8

(divide right by # of r)

r = 3.8/3.8

r = 1

Scorpion4ik [409]
35% off means 35% of the original price, $625.00, will be subtracted from that original price. 35% is equal to 0.35.

$625.00 - $625.00(0.35) = $625.00 - $218.75 = $406.25
