7. Identify the explicit formula for the sequence given by the recursive formula

 B) f(n) = 30 - 8(n - 1)

Step-by-step explanation:

Explicit formula is of the form:    where

Given: f(1) = 30  --> this represents the first term = 30

          f(n - 1) - 8   --> this means the previous term minus 8 thus d = -8

= 30 + (-8)(n - 1)

    = 30 - 8(n - 1)

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%

the homeowners insurance cost for a 115,000 wood frame house is 80,500.

step-by-step explanation:
