Answer:
$330
Step-by-step explanation:
A simple way to do it is to see that it already has 20 on the graph. 20 is half of 40, so that stands to reason that $165 from 20 hours turns into $330 from 40 hours since it is double the work double the money.
Answer:
Jason is 14 year old.
Step-by-step explanation:
Given: Joe, John and Jason are each a year apart in age.
Sum of their age is 39.
Lets assume the age of Joe be x
∴ Age of Jahn will be 
And age of Jason will be 
Now, putting up an equation for the sum of their age.
∴ 
Opening the parenthesis.
⇒
⇒
Subtracting both side by 3
⇒ 
Dividing both side by 3
⇒
∴ 
Hence, Joe is 12 year old.
Next subtituting the value of x to find age of Jason and John.
Jason= 
∴Jason= 14 years.
John age= 
∴ John Age= 13 years.
Hence, Jason is 14 year of age.
We will use the equation:
r t = 3/4 r ( t+12 ) /:r
t = 3/4 t + 9
t - 3/4 t = 9
1/4 t = 9
t = 9 * 4 = 36 minutes ( takes a trip to the market )
36 + 12 = 48 minutes
The ride home takes 48 minutes.
Yes, by the time you add up all estimations, you must add taxes.
What are the answer choice?? Would love to help you. :)
