Answer: 1. A. y=17x
2. $59.50
Step-by-step explanation:
1. In the table , it can be seen that as x increases y increases with the proportionality constant k =
,.
Equation of direct variation between x and y : 
Put k= 17 , we get
, which is the required equation.
So correct option is "A".
2. To find : The charge for renting a machine for 3.5 hours.
Put x= 3.5 in above equation , we get

Hence, the charge for renting a machine for 3.5 hours is $59.50.
So correct option is "B".
A percent is 1 in 100 or 1/100
240km-200km=40km it increased 40km in the last 2 years
40/200=1/5=20/100=20%
Answer:
$9.50/hour
Step-by-step explanation:
All you need to do is 71.25/7.5 (money earned ÷ hours worked) to get 9.5!
