Answer: 28
Given ; The ratio of dye to pounds of clothing is constant. A worker develops the chart below to show the amount of dye needed for different amounts of clothing.
Dyeing Weight of clothing (pounds) 22 28 34 36
Cups of dye 5.5 6.5 8.5 9
To Find : which weight of clothing is the ratio of weight to dye different from the other ratios
Solution:
Dyeing Weight of clothing (pounds) Cups of dye
22 5.5
28 6.5
34 8.5
36 9
22/5.5 = 4
28/6.5 = 4.31 ≠ 4
34/8.5 = 4
36/9 = 4
28 , 6.5 should be either 28 , 7 => 28/7 = 4
or 26 , 6.5 as 26/6.5 = 4
28 , 6.5 is different from the other ratios
