"of the computers" tells you that the answer is a percent of ALL of them.
How many computers are there altogether ? (36 + 54) = 90 computers.

How many laptops are there ? ===> 54

What percentage of the total of 90 is 54 ?

54/90 = 0.6 = <em>60% </em>.

First find the total number of computers
which is 36+54= 90 total number of computers
use ratio and proportion
56/90= x/100
cross multiply
90x=5400
x= 60% of the computers are laptops

hope this helps

Answer:

When Josh babysits, he chargers a flat fee of $14 plus an hourly rate of $9. How long would Josh need to babysit if he wants to

SpyIntel [72]

Answer:

$\frac{36}{7}$ hours

Step-by-step explanation:

First let's get the flat fee of 14 out of the way, because he wants to earn 86 dollars and the 14 dollar fee is the y intercept.

$86-14 = 72$

We would then divide 72 by the slope (14 per hour) to see how many hours he has to work:

$72/14 \approx5.14285714286$

I would just simplify because this decimal isn't exact

$72/14 = 36/7$

So 36/7 hours
