Answer:
128
Step-by-step explanation:
There is a common difference between consecutive terms, that is
11 - 2 = 20 - 11 = 9
This indicates the sequence is arithmetic with n th term
= t₁ + (n - 1)d
where t₁ is the first term and d the common difference
Here t₁ = 2 and d = 9 , thus
t₁₅ = 2 + (14 × 9) = 2 + 126 = 128
is the constant of proportionality that represents the relationship between the cost, y, to the number of pounds of potatoes, x .
<u>Step-by-step explanation:</u>
Here we have , The cost of 2 pounds of potatoes is $3.78. We need to find the constant of proportionality that represents the relationship between the cost, y, to the number of pounds of potatoes, x . Let's find out:
Cost is y & number of pounds of potatoes is x :
, where k is constant of proportionality that represents the relationship between the cost, y, to the number of pounds of potatoes, x .
