C. 7.5
3/4 = .75
7.5/10 = .75
2/3x-1/5=x-1
Add similar elements 23x-15=8x
Subtract x from both sides 8x-x=x-1-x
Simply 7x=-x
Divide both sides by 7 7x = -1
__ __. *Simply: x=-1/7
7 7

Answer:
Step-by-step explanation:
Jude paid 84% of the original price. That comes about because 369.60 is the price he paid which includes as 16% reduction.
84/100 * x = 369.60 Multiply by 100
84x = 36960 Divide by 84
84/84 x = 36960/84
x = 440
So the original price was 440 pounds
