Answer:
4
Step-by-step explanation:
UPC (Universal Product Code) is a numeric symbol used in retail products. UPC has two variants, an 11 digit UPC Type A bar code and and 6 digit UPC Type E bar code.
The given UPC code 78007305233 is an 11 digit UPC Type A bar code.
1) From the right to the left, starting with odd position, we need to assign the odd/even position to each digit.
0 E 0 E 0 E 0 E 0 E 0 [0 stands for Odd, E stands for Even]
7 8 0 0 7 3 0 5 2 3 3
2) Summing up all digits in the odd positions and multiplying the result by 3
(7+0+7+0+2+3)*3 = 19 * 3 = 57
3) Summing up all digits in the even positions
8+0+3+5+3 = 19
4) Summing up the results of step three and four
57 + 19 = 76
5) Now, divide the result of the fourth step by 10. The check digit would be the number which adds the remainder to 10. In our case, upon dividing, 76 by 10 we get the remainder 6. The check digit is the result of 10-6 = 4.
So, she paid (75-17.34=57.66) for the purchase
Or, the jeans costed 57.66-3.26=54.4 (prize minus sales tax)
But she got a 10 dollars off! so that means that the jeans actually costed 64.4
now, the 64.40 was the prize discounted by 30%:
64.40=(100-30)%*x
where x was the original prize
64.40=0.7x
644=7x
x=644/7
x=92
so the original prize was 92 dollars.
