h(x) = 2x - 1
Let x = -1
h(-1) = 2(-1) -1
h(-1) = -2-1
h(-1) = -3
Well you subtract d from both sides with would make 2D-4=-8. Then you subtract four to both sides which is -12. Then you divide -12 by 2D which is 6. D=-6
Find the sale price by multiplying the original price by 70% then add the two prices together to get the total.
799 x 0.70 = 559.30
549 x 0.70 = 384.30
