So for number 3, so for every 15 he earns, he saves 6 so 
15:6=5:2
then he earns 75 and saves x
5 times what=75
5 times 15=75
2 times 15=30
so the ration is 75:30
he saved $30
then 
write a real life proportion
so rob has a pattern to make,
for every 5 blue tiles, he puts down, he must put down 7 green tiles,
he needs to fill a sqare area that is 12 feet in legnth and width
each tile is 1 foot
how many blue tiles will he need
so 5+7=12
area=12 times 12
area=144
so the number of tiles is 144
so blue=5/12
so 144 times 5/12=60 blue tiles
        
             
        
        
        
Answer: After working for 33  hours a week
 hours a week
Step-by-step explanation:
      Let us write equations to represent these two places. Let x be hours worked and y be money earned.
    Tim Hortons:
$200 + $5x = y
     McDonalds:
$300 + $2x = y
     Now, to find the conditions of which Tim Hortons is the better employer (on the basis of money earned) we must find the interval that Tim Hortons pays more. This can be found by setting up another equation, or by graphing. I have shown both. <em>See attached for the graph</em>.
$200 + $5x > $300 + $2x
$5x > $100 + $2x
$3x > $100
x > 
x > 33.3334
     Tim Hortons is the better employer after an employee has worked for 33  hours a week.
