After 15 number of visits, both plans cost $55 and at the 10th visit, plan 2 is more expensive than plan 1.
Arithmetic sequence is a sequence of numbers where the numbers are arranged ion a definite order such that the difference of two consecutive numbers is a constant. This constant of difference is called common difference which is commonly denoted by the letter 'd'.
Part A :
From the table, we can clearly express both plans as Arithmetic sequence.
Plan 1 : First term, a = 27 and common difference, d = 2
Plan 2 : First term, a = 41 and common difference, d = 1
Let n be the number of visits that both plans costs the same.
27 + 2(n - 1) = 41 + (n - 1)
27 + 2n - 2 = 41 + n - 1
2n + 25 = n + 40
n = 15
Cost = 41 + (15 - 1) = $55
Part B :
We have to find the 10th term.
For plan 1 :
Cost at 10th visit = 27 + 2(10 - 1) = $45
For plan 2 :
Cost at 10th visit = 41 + (10 - 1) = $50
The plan 2 is more expensive at the 10th visit.
Hence at the 10th visit, plan 2 is more expensive.

Step-by-step explanation:
From the looks of it, Plan A is 25 + 2x and plan B is 40 + x.
Part A:
25 + 2x = 40 + x
x = 15
plug in any: 40 + 15 = $55
Part B:
Plan A = $45
Plan B = $50
Plan B is $5 more expensive.
Answer:
Step-by-step explanation:
10 divided by 12= 0.83
0.83 times 5= 4.16 or 26/625
|18 + 7| / 10 is equal to 25/10
|-16 + 26| / 6 is equal to 10/6
25/10 can be multiplied by 3 to get 75/30
10/6 can be multiplied by 5 to get 50/30
75/30 - 50/30 = 25/30 and that simplifies to C) 5/6

Answer:
118 5/12
Step-by-step explanation:
9 2/3 × 12 1/4 = 2 + 9·3/3 ×1 + 12·4/4 = 29/3 × 49/4 = 29·49/3·4 = 1421/12 5 + 118·12/12= 118 5/12
