Question

Faster. She starts with $200 and plans to save $60 every week, x.

Write an expression for the amount of money she saves after x weeks.



How many weeks will it take Emily to save for the PS5? Who was faster, Emily or Benjamin? Explain your answer.

Answer 1

It will take Emily 5 weeks to save enough money for the PS5.

Emily plans to save $60 every week, and she starts with $200.

The expression for the amount of money she saves after x weeks (S(x)) can be given by the formula:

S(x)=200+60x

To find out how many weeks it will take Emily to save for the PS5, you need to set S(x) equal to the cost of the PS5. Let's assume the cost of the PS5 is $500:

200+60x=500

Now, solve for x:

60x=300

x=5

So, it will take Emily 5 weeks to save enough money for the PS5.
