ANSWER:
The table for Ms. Jello shows a proportional relationship, because Ms. Jello reads at a proportional rate of 26 pages per hour
In Mathematics, a proportional relationship between two variables occur when the two quantities vary with each other.
Given both tables let's check for the number of pages read in an hour.
Let's use constant of proportionality K, to solve.
Ms. Jello;
208 pages is proportional to 8 hours
208 = K8
K = 208 ÷ 8 = 26
156:6
156 = K6
K = 156 ÷ 6
K = 26
234:9
234 = K9
K = 234 ÷ 9
K = 26
This table for Ms. Jello shows a proportional relationship, because 26 pages are read in an hour
Now let's check for the second table
Ms. Valesquez:
168:8
168 = 8K
K = 168 ÷ 8
K = 21
120:4
120 = 4K
K = 120 ÷ 4
K = 30
348:12
348 = 12K
K = 348 ÷ 12
K = 29
The table for Ms. Valesquez does not show a proportional relationship.
