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:
Answer:
3(25) + 5 = 80
x = 25
Step-by-step explanation:
3x + 5 + 75 + x = 180
4x + 80 = 180
4x = 100
x = 25
3x + 5
3(25) + 5 = 80
x = 25
Answer:
2:1 or 2
Step-by-step explanation:
<em>*** </em>(Ratios can be written as " a : b", or can be written as a fraction " a / b".
>> therefore 10/5 can be simplified to 2/1 )<em>***</em>
For every 10 notebooks, there are 5 ballpens.
Therefore, for every 2 notebooks there is 1 ballpen (The simplification).
<u><em>EXTRA: </em></u>
**Also remember that the ratio of notebooks to ballpens cannot be reversed into ballpen to notebook ratio, because this would change the meaning.
2/1 is not the same as 1/2 **
