Answer:

Kameryn will have more words typed than Joe when the number of minutes exceeds 34.

Explanation:

Let

x -----> the number of minutes

y ----> the total words typed

we know that

Kameryn


y=75x -----> equation A

Joe


y=60x+510 -----> equation B

Solve the system of equations by substitution

Substitute equation A in equation B and solve for x


75x=60x+510


75x-60x=510


15x=510


x=34\ minutes

That means

For x=34 minutes

The amount of words written by Kameryn and Joe are the same.

therefore

For x > 34 minutes

Kameryn will have more words typed than Joe when the number of minutes exceeds 34.
