Answer:
28 cupcakes and 12 muffins were sold.
Step-by-step explanation:
First identify what variable to use for cupcakes and muffins.
X→ Cupcakes
Y→ Muffins
Then you need to write two equations.
X+Y= 40
X= 4+2Y
Since you have the value of X you need to substitute.
(4+2Y)+Y= 40
Combine like terms.
4+3Y= 40
Now use Subtraction Property of Equality.
4+3Y= 40
-4 -4
Now you have 3Y= 36
You have to use Division Property of Equality now.
=
If done correctly you should get Y= 12
Afterwards you must get 12 and subtract it from 40.
40-12= 28
28 is the amount of cupcakes sold.
To check you can see that 28 is equal to 12×2+4.
Hope this helped!
2.5*6=15 therefore A is the answer, because, 60/10=6 and then 2.5*6=15 so A is your answer.
