Ahouse is purchased for $375000 and has gained 12% for the last 5 years. what is it now ?

  $420,000

Step-by-step explanation:

The added percentage can be turned into a multiplier to make the problem easier.

  value + 12%×value = value(1 +0.12) = 1.12×value

  1.12×$375,000 = $420,000

It is $420,000 now.

step-by-step explanation:

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
