Monica and Lauren know that they will need a lot of money in order to make the purchases necessary for a successful bakery. They

xxTIMURxx [149]

Based on the model, the total amount of money in the joined account after the 5 weeks is $767.30

<h3>What are linear equations</h3>

Linear equations are equations that have constant rates

A linear equation is represented as:

y = mx+ b

In this case,

m represents the deposit per week
b represents the initial deposit

So, the linear equations are:

y =153.46x --- for Monica
y = 128.90+ 127.68x -- For Lauren

To calculate the number of weeks, when they have the same amount, we equate both equations

$153.46x = 128.90 + 127.68x$

Collect like terms

$153.46x -127.68x= 128.90$

$25.78x= 128.90$

Solve for x

$x= 5$

Substitute 5 for x in

$y = 153.46x$

$y = 153.46 * 5$

$y = 767.30$

Hence, it will take 5 weeks for both accounts to have the same amount of $767.30
