Question

Cameron earn's $7 per hour at her after school job. The total amount of her paycheck varies directly with the amount of time she works. Wirte a direct variatin equation of money "y" that she earns for working "x" hours.

Answer 1

Proportionality equation:
`y=7kx`

Linear equation:
`y=7x`

Explanation:

So the amount that Cameron earns = 7/hr

Hours = x

And total earned amount = y

So we can form an equation from this for the total amount:

`y=7x`

But the question asks us for a proportionality equation so:

Proportionality constant = k

So we get the equation:

`y=7*k*x`

Answer 2

`\[y = 7kx\]` where k is the constant of proportionality

Explanation:

Total amount earned by Cameron every hour = $7

Total amount varies directly with the number of hours she works.

Let the total amount earned by Cameron be represented by y.

Let the total number of hours worked by Cameron be represented by x.

Then y is directly proportional to 7*x.

Let k be the constant of proportionality.

=>
`\[y = k*7*x\]`

=>
`\[y = 7kx\]`
