Hello!
First we have to define a variable.
Let x stand for the price of a granola bar
Then we have to make our equation
1250x + 25 = 800
This is the equation because the price for all the granola bars and delivery was $800
Now we solve it
Subtract 25 from both sides
1250x = 775
divide 1250 from both sides
x = 0.62
The cost for a granola bar is $0.62 or 62 cents
Hope this helps!
