14+16 1. Break it down 14 is equal to 10+4 16 is equal to 10+6 2. Add the biggest numbers together first 10+10 = 20 3. Add the smaller numbers together 6+4 = 10 4. Add all of the numbers together 20+10 = 30

x = 70/10 = 7%
Answer:
The amount of tax Zoe would pay if she bought a book from Store Y would be $1.44.
Step-by-step explanation:
I got this because to find the tax you need to pay, you take the percentage and move the decimal point twice to the left; in this case it would go from 8% to 0.08 because the decimal point is at the end of the number. You multiply the 0.08 by the amount the book costs, and you get the amount of tax you have to pay.
The correct answer would be $7.53
