Question

Fatima is saving up to buy a $300 bike.she saves $25 each week from her babysitting money.write a linear equation that represents the amount Fatima still has to save after x weeks?Let y represent the amount you have to save after x weeks.

Answer 1

300 divided by 25=12
X times Y=$300

Answer 2

Answer:

$\text{y}=300-25\text{x}$

Step-by-step explanation:

Given: Fatima is saving up to buy a $300 bike.she saves $25 each week from her babysitting money.

To Find: a linear equation that represents the amount Fatima still has to save after x weeks, Let y represent the amount you have to save after x weeks.

Solution:

Amount Fatima saving for bike $=\ 300$

Amount saved by fatima each week $=\ 25$

Let the number of weeks $=\text{x}$

Let the amount saved after $\text{x}$ $\text{weeks}$ $=\text{y}$

Now,

amount have to be saved after $\text{x}$ $\text{weeks}$

                                                    $=300-\text{amount saved in x weeks}$

                                                    $=300-25\text{x}$

Linear equation for amount saved

                                                 $\text{y}=300-25\text{x}$

linear equation that represents the amount Fatima still has to save after  $\text{x}$ $\text{weeks}$ is $\text{y}=300-25\text{x}$
