A: For every cup of red paint she mixed, she added 3 cups of blue paint to make a shade of purple.
 B: For every cup of blue paint, Lara should mix in 1/3 of a cup of red paint to make the shade of purple. This is because the ratio is 3:1, and that means to work out how many cups she would need for only one cup of blue paint, you divide both sides by 3.
 C: 48 ÷ 6 = $8 per cup.
