Question

In art class students are mixing blue and red paint to make purple paint. Carlos mixes 4 cups of blue paint and 7 cups of red paint. Kaj mixes 2 cups of blue paint and 3 cups of red paint. Use Carlos and Kaj’s percent of red paint to determine whose purple paint will be redder.

Answer 1

Carlos' paint will appear redder.

Explanation:

Carlos mixed 4 cups of blue paint and 7 cups of red paint. To find the percent of red paint, we divide the amount of red paint by the total amount of paint (blue + red) and multiply by 100. The total amount of paint in Carlos' mixture is 4 + 7 = 11 cups. So, the percent of red paint in Carlos' mixture is (7 / 11) * 100 = 63.64%.

Kaj mixed 2 cups of blue paint and 3 cups of red paint. Similarly, we divide the amount of red paint by the total amount of paint (blue + red) and multiply by 100. The total amount of paint in Kaj's mixture is 2 + 3 = 5 cups. So, the percent of red paint in Kaj's mixture is (3 / 5) * 100 = 60%.

Comparing the percentages, we see that Carlos' purple paint will be redder since it has a higher percentage of red paint (63.64%) compared to Kaj's mixture (60%), therefore, Carlos' purple paint will appear redder.
