3.56 +/- 0.011 = ( 3.549, 3.571). This is the answer.
1. x = 15120/12 = 1260 (monthly salary)
2. 1200 x 0.05 = 60 (raise)
Check: 1200+60=1260
You have everything right. If you look, it says Y is distance from home, and X is the time they spent driving.

Step-by-step explanation:
Given
Yearly Cost for members; 
Required
Determine the yearly cost for non members
From the question, we understand that:
<em>A non member pays $0.20 for each game;</em>
Yearly cost is then calculated as thus;
y = Amount * Number of Games
Where:
Amount = $0.2 and Number of Games = x

Convert 0.2 to fraction

Divide the numerator and the denominator by 2


<em>Hence, the yearly cost for non members is </em>

Answer:
Step-by-step explanation:
Set this up as ratio of vinegar to oil in fraction form:

That's what we're given. If we are looking to find how much oil he needs if he's using 9 ounces of vinegar, then 9 goes on top with the vinegar stuff and x goes on bottom as the unknown amount of oil:

Cross multiply to get
5x = 90 and
x = 18
Which you probably could do without the proportions. If he is using 5 ounces of vinegar and double that amount of oil, then it just makes sense that if he uses 9 ounces of vinegar he will double that amount in oil to use 18 ounces.
