Back

1 and 19/24 mi

Front

What does the constant of proportionality represent in a relationship between the number of books purchased and total cost?

Back

It represents the cost per book, which is constant.

Front

If the cost of health insurance increases by 8% and the new cost is $28.35, how do you find the original cost?

Front

What is the formula to calculate the total distance in a relay race with different segments?

Back

Total distance = distance1 + distance2 + distance3.

Front

How do you calculate the percentage increase in a cost?

Back

Percentage increase = (new cost - original cost) / original cost × 100.

Front

What is the process to solve for the original price before a percentage increase?

Back

Original price = new price / (1 + percentage increase as a decimal).

Front

If a table shows a relationship between books and cost, how can you determine if it is proportional?

Back

Check if the ratio of cost to number of books is constant.
