The primary advantage of using an algorithm (rather than a heuristic) is that it:

a. Always yields a correct solution if executed correctly
b. Is widely applicable to many different content domains
c. Can be easily used by the typical 6-year-old child
d. Never takes more than five minutes to complete

Question 2

Sarah needs to solve this word problem:
A sweater in a store is originally priced at 40, but the price tag is marked One-half off. The sweater is placed on a rack marked Five dollars off the sale price. How much does the sweater cost now?
Sarah knows how to find one-half of a number; she also knows how to subtract one number from another. She uses both of these operations to arrive at the correct answer of 15 . Which one of the following best describes Sarah's approach to problem solving?

a. Drawing an analogy
b. Availability
c. Working backward
d. Combining algorithms
