What is the combined total of printers donated to Latin America and to underprivileged communities?

• A. 550+
• B. 500+
• C. 450+
• D. 600+

Answer: (B)

Interpreting these donation totals relies on the “X+” notation: it means the actual amount is greater than X. If the combined total of printers donated to Latin America and to underprivileged communities is known to exceed 500, then the statement that it is more than 500 must be true. That makes it the tightest, most informative bound we can reliably assert from the given information.

Higher bounds like more than 550 or more than 600 require the total to be larger than it’s guaranteed to be, so those aren’t necessarily true. The bound of more than 450 is true as well, but it’s less specific than “more than 500.” So the best fit given the information is that the combined total is over 500.
