Help Me ASAP!!!!! PLS

Answer 1

Answer:

C: y = 115,000(1.05)x

Step-by-step explanation:

(havn’t actually did any math, but this is just process of elemination.)

{I’m just looking at the end of these, because the start is all the same}

if the number with the (perenthese) is below 1, it is a decreas, and the problem says it’s increasing by 5%. (1.5) Is equal to 50% increase so that means your answer would be (1.05) Because anything times 1 is the larger number, but when u add that 0.5, it’s raising the number up by 5%.

Answer 2

Answer:

C. y = 115 000(1.05)^x

Step-by-step explanation:

The formula for the amount accrued on an investment earning compound interest is

$A = P(1 + r)^{t}$

where

P = the amount of money invested (the principal)

r = the interest rate per period expressed as a decimal fraction

t = the number of periods

In this problem,  

P = $115 000

r =  5 % = 0.05

By 2010, Luca's house will have increased in value for three years. Its value will be  

$A = 115000(1 + 0.05)^{3}\\\text{The correct formula for the value of his home x years after 2010 is}\\ y = 115000(1.05)^{x}$
