Answer:
1. The ratio is 6:14 or 6/14, 3:7 or 3/7.
2. 2/8 or 1 out of 4.
4. At approximately 16c
a cup, Folgers Coffee is better value than Seattle's Best which costs 18c a cup.
Step-by-step explanation:
1. Talley, ratios work like fractions. The ratio is 6:14 or 6/14, which reduces to 3:7 or 3/7.
2. If 8 out of 10 prefer Crest, then 2 out of 10 do not. The ratio of those who do not prefer Crest (2) to those that do prefer Crest (8) is 2/8 or 1 out of 4.
4. To find the respective value per cup, divide the prices give by the number of cups they represent. We shall represent Folgers Coffee by f and Seattle's Best by s
.
f = 12.88/80
= 0.161
Folgers Coffee is approximately 16
c per cup.
s = 9.00/50
s = 0.18
