Answer:

$675

Step-by-step explanation:

Let

x = original price of laptop

Discount = 10%

Actual price paid = x - 10% of x

= x - .10x

= .90x

Cost of mouse = $13.99

Total amount paid = $621.49

Total amount paid = actual cost of laptop + Cost of mouse

621.49 = .90x + 13.99

621.49 - 13.99 = .90x

607.5 = .90x

x = 607.5 / .90

= 675

Original cost of the laptop = $675

Answer:

y=5x

Step-by-step explanation:

The table is given as:

x | y

2 | 10

4 | 20

6 | 30

8 | 40

A proportional relation satisfy the relation: $y=kx$

We can substitute any x value with the corresponding y-value and solve for k.

When x=2,y=10

This implies that:

$10=2k$

Divide both sides by 2 to get:

$k=5$

Hence the equation is $y=5x$
