So all you need to do is to multiply 12.49 by 1.13 ( since 1.00 is the price and 0.13 is the added tax rate), which gives you $14.11
The notation per capita simply means that the number is
divided by the total population. Therefore the number of McDonald’s per capita
in Canada 2013 is:
McDonald’s per capita = 1427 / 35,160,000
<span>McDonald’s per capita = 4.06 x 10^-5</span>
Average speed of cyclist = x
average speed of car = 3x
x = 225/5
x = 45km/h
3x = 3(45)
3x = 135km/h
average speed of cyclist = 45km/h
average speed of car = 135km/h
Given :-
- y varies directly as x, and y=14 when x=4.
To Find :-
- the value of y when x=9 .

- y = 7/2*9
- y = 63/2
- y = 31.5
P,Q,R can't be 0, because their product is nonzero. Either of S and T could be 0, but the third one only works if S is 0.
