Answer:
the first one
the third one
and the forth one
Step-by-step explanation:
they all add up to the same amount
Answer:
The amount of that tip is $19.20
Step-by-step explanation:
Turn the percent into a decimal, 20% is now .20.
Multiply- 96×.20= 19.20
You just need to list the factors of all 3 numbers, and see what numbers they have in common!
15: 1,3,5,15
18: 1,2,3,6,9,18
12: 1,2,3,4,6,12
so in all you can say that the common factors of 15,18,12 is: 1 and 3
Answer:
B. Fₙ₊₁ = Fₙ - 0.15Fₙ + 5
Step-by-step explanation:
The options above are examples of recurrence relations where the present state Fₙ₊₁ is dependent on the previous state Fₙ.
For each year that a customer does not file a claim, their rate is reduced by 15%
Fₙ-(15% of Fₙ)= Fₙ-0.15Fₙ
A credit of $5 is also awarded, therefore:
Fₙ - 0.15Fₙ + $5
Therefore If a customer did not file a claim in the nth year, the customer's rate in the (n + 1)th year as a function of their rate in the nth year is given by:
Fₙ₊₁ = Fₙ - 0.15Fₙ + 5
