Not sure why, but I wasn't able to post my solution as text, so I've written it elsewhere and am posting screenshots of it here.
In the fifth attachment, the first solution is shown above the second one.
For this case, the first thing we must do is define a variable.
We have then:
x: number of muffin plates
We now write the expression that models the problem.

Substituting for x = 0 we have:
Answer:
There are 0 lemon muffins
d: 0

Answer:
1. 50000
2.
i 274625000cm
ii 274.625m
Step-by-step explanation:
1. Area of a rectangle: length*width
250*200=50000cm
2. Volume of a cube: length^3
i 650^3=274625000cm
ii 650 cm=6.5m; 6.5^3=274.625m
