Question

Suppose a college student pays $500 for tuition fees. However, she also has to pay $350 for her textbooks (ouch!). What percent of her total education costs does she pay for her books?

Answer: Her books represent
percent (as a decimal) of her total costs.

Write your answer to the nearest tenth of a percent, but in decimal form. For example, if you saved 34.67%, you would round to 34.7% and enter .347 as your answer.

Answer 1

Tuition costs = $500
Textbook costs = $350
Total cost = 500 + 350 = $850
Percent of costs due to textbooks = 100*(350/850) = 41.1765%
Her books represent 41.2% of her total costs.

Answer: 0.412
