Answer:
The function that represents the cost in cents of ‘d' dozen gumballs is y = 10d .
Step-by-step explanation:
As given
If 30 gumballs can be purchased for 3 dollars .
i.e
30 gumballs = $3
Now find out the cost of one gumballs .
As 1 dollar = 100 cents
1 gumballs = 10 cents
Thus the cost of one gumball is 10 cents .
As d = dozen gumballs.
Let us assume that the cost for ‘d' dozen gumballs = y
Than the function becomes
y = 10d
Therefore the function that represents the cost in cents of ‘d' dozen gumballs is y = 10d .

Step-by-step explanation:
Big Video: y = 2.49x + 9.99
Main Street: y = 1.79x + 20.49
easiest way to solve would be to graph and find the point of intersection or set 2.49x + 9.99 and 1.79x + 20.49 equal to each other
2.49x + 9.99 = 1.79x + 20.49
subtract 1.79x from each side to get:
.70x + 9.99 = 20.49
subtract 9.99 from each side to get:
.70x = 10.50
divide each side by .70
x = 15
