To find the total cost of the new laptop, we can use the information given. We know that Laura has saved 20% of the total amount needed, which is equal to $80.

To find the total amount needed, we can set up a proportion. Let's represent the total cost of the laptop as "x".

20% of x = $80

To convert the percentage to a decimal, we divide it by 100:
0.20x = $80

To solve for x, we can divide both sides of the equation by 0.20:
x = $80 / 0.20

Performing the division, we find:
x = $400

Therefore, the new laptop costs $400.

Ok thanks

0.2x = 80

Solve for x.
