Answer:
B
Step-by-step explanation:
The diagram shows four points through which the line of proportional relationship should pass. One of these points has coordinates (8,28).
The line representing proportional relationship is always straight line passing through the origin and has the equation
where k is the coefficient of proportionality.
Substitute coordinates of known point into the equation:
so the coefficient of proportionality is equal to
Answer:
<em>The products did cost $173.9 in 2010</em>
Step-by-step explanation:
<u>Exponential function</u>
Two variables y and x are related as an exponential function if they comply:
where C is the initial value of F, r is the ratio, and k is a proportional constant.
The situation described in the question is modeled as
Where F is the final value of the cart of groceries in 2010, C = $150 is its value in 2005, r is the yearly rate of increase. n is the number of years
. So
If we set n=5 (from 2005 to 2010):
The products did cost $173.9 in 2010
