Gerhard Tintner’s brief book review evaluates Charles H. Mergendahl and Le Baron R. Foster’s pamphlet as a teaching resource. Its central judgment is that the exercises offer a useful supplement to instruction in financial mathematics. Tintner defines both the material’s scope and its intended audience:
This book contains 100 problems in consumer credit for high school and for college courses in the mathematics of finance.
The review follows the pamphlet’s instructional sequence: an introduction explains the meaning of consumer credit and introduces the principal concepts and calculations, after which the exercises provide opportunities for practice. Tintner calls the introduction adequate; his stronger praise concerns the quality of the problems:
The problems are very well thought out, interesting and stimulating.
This assessment joins pedagogical design to student engagement. The exercises matter not simply because they supply calculations, but because Tintner finds them thoughtfully constructed and capable of stimulating interest. His closing recommendation places the pamphlet alongside textbooks in a mathematics-of-finance course. The review’s relevance is thus practical and curricular: it endorses an exercise-based aid connecting consumer credit with financial calculation. It offers no examples of the problems or detailed account of their methods, so its positive verdict remains a concise teaching recommendation rather than a developed analysis of consumer-credit economics.
