The population of a town was 10,000 in 2018. Each year the town's population grows by 23%. Let x=0 be the year 2018. Create the

Naily [24]

Answer:

$f(x)=10000(1.23)^x$

Step-by-step explanation:

We are going to apply algebra to solve for the exponential growth

we know that the expression for the exponential formula is

$y = ab^x.$

where

a = the amount before measuring growth or decay

= 10,000

r = growth or decay rate = 23%= 0.23

x = number of time intervals that have passed

since this problem is on the growth we are going to replace "b" with (1+r), likewise for decay (1-r)

hence the formula becomes

$y = a(1+r)^x.$

$f(x)=10000(1+0.23)^x \\\\f(x)=10000(1.23)^x$

The expression that will give the population value is

$f(x)=10000(1.23)^x$

A package of strawberries costs 1.50 while they are in season and 2.25 when they aren't in season. What is the percent increse.

PIT_PIT [208]

The answer is 50%.

Divide 2.25 by 1.50. That equals 1.5. That’s the equivalent to 50% because if you subtract 1 from 1.5 and multiply by 100. You get the same answer. Only do that for numbers greater than one, otherwise it won’t work

scZoUnD [109]

Answer:

The shipping and handling charge that Bryce paid is $109.65

Step-by-step explanation:

Given as :

The online price of the treadmill = $510

The charge of shipping and handling = 21 $\dfrac{1}{2}$ % of online price

Let The shipping and handling charge that Bryce paid = $x

<u>Now, According to question</u>

∵ The charge of shipping and handling = 21 $\dfrac{1}{2}$ % of online price

So, x = $\dfrac{43}{2}$ % of $510

Or, x = $\dfrac{43\times 510}{100\times 2}$

Or, x = $109.65

The shipping and handling charge that Bryce paid = x = $109.65

Hence,The shipping and handling charge that Bryce paid is $109.65 Answer
