Answer
Explanation:
Step1: Recall the meaning of percentage as a ratio
A 7% sales - tax means for every 100 units of the purchase price, 7 units are paid as tax.
Step2: Check option A
For a $10 purchase, the tax is $10\times0.07 = 0.7$ dollars, not $7$ dollars. So option A is incorrect.
Step3: Check option B
For a $1000$ purchase, the tax is $1000\times0.07=70$ dollars, not $7$ dollars. So option B is incorrect.
Step4: Check option C
For a $100$ purchase, the tax is $100\times0.07 = 7$ dollars, not $70$ dollars. So option C is incorrect.
Step5: Check option D
For a $1$ purchase, the tax is $1\times0.07=0.7$ dollars or 70 cents. So option D is correct.
Step6: Check option E
For a $10$ purchase, the tax is $10\times0.07 = 0.7$ dollars or 70 cents, not 7 cents. So option E is incorrect.
Step7: Check option F
For a $1000$ purchase, the tax is $1000\times0.07 = 70$ dollars. So option F is correct.
Step8: Check option G
For a $10$ purchase, the tax is $10\times0.07=0.7$ dollars or 70 cents. So option G is correct.
Step9: Check option H
For a $1$ purchase, the tax is $1\times0.07 = 0.07$ dollars or 7 cents, not 7 cents for a $1$ purchase. So option H is incorrect.
Answer:
D. You will pay 70 cents in sales tax for every $1 purchase. F. You will pay $70 in sales tax for every $1,000 purchase. G. You will pay 70 cents in sales tax for every $10 purchase.
