This graph shows a proportional relationship SHOW
between the number of pallons of gasoline used
(a) and the total cost of gasoline (c).
Find the constant of proportionality (). Using the
Coat of Gasoline
value for r, enter an equation in the form of
C = rg that represents the relationship between
the number of gallons of gasoline used (g) and
the total cost (c).

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.

using pemdas, (order of operations) you'll see the answer is 24.
