To find the unit rate in dollars per quart, divide the total cost by the number of quarts: \( \$7.69 \div 6 \approx \$1.28 \) per quart. Now, if you're looking for quarts per dollar, take the reciprocal of that value: \( 1 \div 1.28 \approx 0.78 \) quarts per dollar. So, you get approximately \$1.28 per quart and about 0.78 quarts for each dollar spent! When dealing with unit rates, it’s easy to make simple mistakes in calculations. A common error is forgetting to divide the figures in the correct order. Always double-check your math! Also, rounding too early can lead to inaccuracies, so try to keep as many decimals as you can until you finalize your answer.
