Which of these is a proportional relationship? A Justin charges $1 for 1 cup of lemonade, $3 for 2 cups of lemonade and $4 for 3 cups of lemonade. B Jared charges $1 for 1 cup of lemonade, $2 for 2 cups of lemonade and $3.50 for 3 cups of lemonade. C Jasmyne charges $1 for 2 cups of lemonade, $2 for 4 cups of lemonade and $3 for 6 cups of lemonade. D Jessica charges $1 for 1 cup of lemonade and $2 for anyone who wants 2, 3 or 4 cups of lemonade.

C

Step-by-step explanation:

Because the ratios are equal, it’s a proportionate relationship. Each price ($1 for 2, $2 for 4, $3 for 6) if put into fractions (1/2, 2/4, 3/6) each equal half.

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.

24

step-by-step explanation:

30% × 80 = 0.30 × 80 = 24
