A data plan has 500 MB free and $0.10 per additional MB. If you use 1,200 MB in a month, what is the overage charge?

• A. $70
• B. $120
• C. $100
• D. $200

Answer: (A)

With a data plan that includes a free allotment and a per-MB charge for extra use, you only pay for what goes beyond the included amount. Subtract the free 500 MB from total usage: 1,200 MB − 500 MB = 700 MB overage. Each extra MB costs $0.10, so multiply: 700 × $0.10 = $70. The overage charge for the month is $70.
