Math help with algebra please!?
A Crate containing 36 grapefruit has a total mass of 10kg. Then 10 grapefruit are removed, the total mass is 8kg. Determine the mass of the crate and the mass of one grapefruit. Answer accurate to 1 decimal place.

Please show full solution. Thank you.

-
Let c = the mass of the crate, and g = the mass of one grapefruit

c + 26g = 10
c + 16g = 8

10g = 2
g = 1/5

c + 3.2 = 8
c = 4.8

The crate has a mass of 4.8 kg, and each grapefruit has a mass of 0.2 kg.
