During a radio contest, $50 is added to the prize money each time a caller answers the contest question incorrectly. the first
caller has a chance to win $100. which equation represents the amount the 10th caller receives if this caller is the first to
answer the question correctly?
a10=100+(10-1)50
a10=50+(10-1)100
a11=100+(11-1)50
a11=50+(11-1)100

The expression is   = 100+(10 - 1)50 .

Step-by-step explanation:

Given as :

The amount of money added as prize money =  $50

The amount that first caller will win =   = $100

Let The amount that 10th caller win = $A

∴ common difference for the callers amount = $50

Now, According to question

The given statement is in arithmetic expression

So, For A.P , The nth term is written as

nth term = first term  + (n - 1) × common difference

I.e = +  (n - 1) × common difference

Here n = 10

Or, A = $100 +  (10 - 1) × 50

So, The expression =   = 100+(10 - 1)50

Hence, The expression is   = 100+(10 - 1)50 . Answer

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
