Answer: 10.5 is my guess

Step-by-step explanation:

1. 30% = 8.4

100 x

cross multiply

30(x) = 840

divide both sides by 30 = 28

2. 37.5% = y

100 28

cross multiply

1050 = 100y

divide both sides by 100 = 10.5

Kameryn types 75 words per minute and is just starting to write a term paper. Joe already has 510 words written and types at a s

AnnZ [28]

Answer:

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

Step-by-step 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.
