May 30th.
Since the date is past the 25th day of the month so buyers get another month for the cash discount. The cash discount ends on the 10th day of the SECOND month so the credit period will be 20 days after the discount period.
7 goes into 11 one time, which leaves you with 1 4/7.
I would say tablets because they have had a steady increase year by year
¹/₆(-15d + 6) < ²/₃(12d + 15)
¹/₆(-15d) + ¹/₆(6) < ²/₃(12d) + ²/₃(15)
-1¹/₂d + 1 < 8d + 10
+ 1¹/₂d + 1¹/₂d
1 < 9¹/₂d + 10
- 10 - 10
-9 < 9¹/₂d
²/₁₉(-9) < ²/₁₉(9¹/₂d)
⁻¹⁸/₁₉ < d
d > ⁻¹⁸/₁₉
Solution Set: {x ∈ x > ⁻¹⁸/₁₉}, (⁻¹⁸/₁₈, ∞)
Factor the expression:
-1/6*6(x-2y)
Divide by 6
-1(x-2y)
Then times by -1
-x+2y
Is your answer
Hope this helps
