Cody's rent is increasing by $51 per month starting next year. That is an increase of 15% from his current monthly rent. Let r r

Inessa05 [86]

Answer:

$r = 43.35$

Step-by-step explanation:

Given

$Current\ Rent = r$

$Increment = 15\%$

$New\ Rent = \$51$

Required

Determine the value of r

The value of r can be set up percentage increase formula as follows:

$\%Increment = \frac{New\ Rent - Current\ Rent}{Current\ Rent}$

Substitute values in the above equation

$15\% = \frac{51 - r}{51}$

Cross Multiply

$51 - r = 15\% * 51$

Convert percentage to decimal

$51 - r = 0.15 * 51$

$51 - r = 7.65$

And the value of $r\ is\ calculated\ using:$

$r = 51 -7.65$

$r = 43.35$

Hence, Cody's current rent is $43.35 monthly

Round 7219 to the nearest thousand

elixir [45]

7000 because if the hundred next to the thousand is below 5 the number will be the same
eg: 3200 the answer will be 3000

but if the number is 5 and higher the thousand will be one extra
eg 1: 3521 the answer will be 4000
eg 2: 4809 the answer will be 5000

Can some explain how to do this.

KatRina [158]

We can simplify the expression by using exponent properties, and we will see that the correct option is the fourth option.

<h3>How to simplify the expression?</h3>

Remember the exponent property:

$\frac{a^n}{a^m} = a^{n - m}$

Here we have the expression:

$\frac{83.9*10^{12}*2.87*10^{-3}}{3.76*10^2}$

We can reorder this to get:

$\frac{83.9*10^{12}*2.87*10^{-3}}{3.76*10^2} = \frac{83.9*2.87}{3.76}*\frac{10^{12}*10^{-3}}{10^2}$

The right side can be simplified to:

$\frac{83.9*2.87}{3.76}*\frac{10^{12}*10^{-3}}{10^2} = 64.04*10{12 - 3 - 2} = 64.04*10^{7}$

Now, we can move the decimal point one time to the left and increase the exponent by one, so we get:

$6.404*10^8$

Then we conclude that the correct option is the last one (where I rounded the expression to only 3 values after the decimal point).
