The answer is z < -8. First of all, you use distributive property to get rid of the brackets. 3(z) = 3z and 3(1) = 3. The left side of the equation is now 3z + 3 + 11. Then, on the other side, -2(z) = -2z and -2(13) = -26. The right side of the equation is now -2z - 26. Then we combine like terms on the left side so we end up with 3z + 14 while the other side is still -2z - 26. We can put all of the z on the left side, so add 2z to both sides and then we have 5z + 14 < -26. We can put all of the “regular” numbers on the right side, so subtract 14 from each side and then we have 5z < -40. Divide each side by 5 and you end up with z < -8!
step-by-step explanation: it originally was $40.00 she has a coupon for 30% 30% of 40.00 is 12 40 • 0.30 = 12 40 - 12 $28 it is now $28 after the coupon her state charges an 6% sales tax on the discounted price 6% of 28 is 1.68 28 • 0.06 = 1.68 28 - 1.68 = 26.32
